that the physical condition of the disk and the documentation will be free of defects upon receipt. However, MK Systems will not be held liable for any consequential, special, indirect or other similar damages or claims. UNDER THE GULF is not guaranteed to work on ALL computers. It has been tested on IBM PC's and several compatibles using EGA and CGA graphics systems. (****************************************************************) WARNING! This documentation has been made to reflect everything in UNDER THE GULF version 1.008. If you have any other version, there may be some discrepancies between the actual program and this documentation. If any questions should arise, contact Matt Kaufman at: MK Systems 19987 Moran Lane Saratoga, CA 95070 (****************************************************************) A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 6 A A GENERAL INFORMATION UNDER THE GULF is a game which simulates the actions of a United States attack submarine. You, the player, are in control of the nuclear powered vessel while the computer controls an opposing fleet of ships and submarines. The game takes place in a 500nm x 500nm area of the Black Sea. In the south west corner, two land masses merge to form a natural canal into the Mediterranean Sea. YOUR MISSION is to keep all of the opposing ships from reaching the open waters of the Mediterranean. Your submarine has complete radar and sonar systems, short and long range torpedoes, defensive systems, mining systems, and extensive navigational capabilities. The use of all of these will be described later in the documentation. The game is based on a TURN SYSTEM. At the end of each turn, the weapons systems and the enemy ships will be updated. Unlike the enemy, however, your submarine is updated constantly. While playing the game, you can make use of the entire turn time, or you may select a command, ADVANCE, to automatically end the turn and update the game for the entire time. This is an important concept to keep in mind while playing the game and it explains why weapons systems and the enemy ships are not updated constantly. Another important thing to keep in mind while playing is that the game is a lot like HIDE AND SEEK. You will see a target one minute, and then it will disappear. This could be caused by any number of events. The important thing to keep in mind is that the computer will continue to project where it thinks that target should be and then give you that information. With that, you can attempt to intercept it. Remember, the enemy is doing the same thing in order to destroy you. The value LOST TIME, which will appear many times during the game, indicates how much time has passed since you last received a definite fix on a target's position. GETTING STARTED UNDER THE GULF can be run on IBM PC / AT / PS2 and compatible computers. To start to the game, first load DOS. Next insert the provided disk into drive A, or you floppy disk drive. At the DOS command prompt, type 'A:' and hit the Return key. Now, simply type 'UTG' and hit return. If you do not wish to run UNDER THE GULF from a floppy drive, you may copy it to either a HARD DISK or a RAM DRIVE. (There will be no significant increase in program execution time when copied to either one of these devices.) Once the game has loaded, you will be presented with a title screen and a short menu of PROGRAM SPEEDS. For the novice, a slower speed is preferable because you can enter more commands during a shorter period of time. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 7 A A USER INTERFACE There are hundreds of variables which will need to be taken into account for you to make decisions during play. For this reason there are three windows on your screen in which you will find information about the Submarine's status. Data in the windows is color coded on monitors which support color or grey scales (ie. Navigation and Radar information each have different colors). The first of these windows, the large window at the top of the screen, is called the MAIN WINDOW. The Main Window's format never changes. Its purpose is to give you an overview of the submarine's status. The contents of this window along with all of the other windows which may appear during play will be explained later on in the documentation. Below the Main window you will find the OPTIONS WINDOW. This window will change in accordance with the commands you select. (ie. if you select a navigation command it will show you all of the information relevant to navigation) There nine completely different windows which will appear in the Options Window. The third window, which will only appear on EGA and VGA systems, is the TACTICAL DISPLAY WINDOW. It contains a map of your surroundings along with a list of all the targets being tracked. If there are any targets which are close enough to appear on the map, then they will show up as arrow (indicating the target's heading) or numbers. The numbers will appear if you are using a MONOCHROME SYSTEM, otherwise the arrows will be present. The color of the arrows will match the color of information about that ship so that you can distinguish between targets. The Tactical Display will contain an immense amount of information. Refer to the key at the lower right hand corner of the window to find out what all of the symbols indicate. If you do not have an EGA or VGA system, you can select the MAP COMMAND under the main menu. It will give you a similar map in the Options Window. On the very FIRST LINE of the screen you can find four things. The first is the number of POINTS you have accumulated. The next piece of information is the TIME that has elapsed during play. (Note: this time and all other times given in UNDER THE GULF are decimal times - IE. 1.5min is equal to 1 minute and 30 seconds) After this you will find the amount of time you have left in your turn. Finally there will be a short message indicating the PROGRAM'S STATUS. Some information is only displayed at the end of each turn. That includes weapons information and other general information which does not appear within any of the standard windows. The WEAPONS UPDATE SCREEN will appear at the end of every turn when there are active torpedoes operating. It will relay all known information about each existing torpedo. Whenever the computer needs to relay information about damage reports, navigation modes, radar/sonar modes or any other extraneous information, you will be presented with the GENERAL INFORMATION SCREEN. It will only appear at the end of a turn. The means for which you will be executing commands is through a simple Lotus 1-2-3 (tm) type menu system. It is located at the bottom of your screen in the MENU WINDOW. You can move the cursor, or the highlight, using the arrow keys. Like Lotus (tm) A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 8 A A menus, a short description of each command will be displayed on the second line of the Menu Window. The information displayed here will change as you move the cursor, in order to match the high-lighted selection. When you have placed the cursor of the item which you would like to select press the ENTER KEY. Instead of using the cursor keys and the return key, you can also simply press the first letter of the item which you want to select. To cancel a selection and go back to the main menu you can press the ESCAPE KEY. Online help is available for every command in UNDER THE GULF. Just place the cursor over the command you need help on and hit the 'H' KEY. At times you will need to ENTER A VALUE. (IE. the speed at which you would like your ship to travel at) When this situation arises the Menu Window will change its appearance and you will be prompted to enter a value. A default value is always provided based on your previous actions. To select the default value, simply press then ENTER KEY. You may also press the 'M' KEY to automatically select the maximum value when one is available (ie. speed, depth and radar range) Maximum values are very useful because maintain maximum setting during times of repair without user input. Pressing the ESCAPE KEY at anytime, while entering a value, will send you back to the main menu. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 9 A A NOTES ON SPECIFIC SYSTEMS NAVIGATION SYSTEM: By far, navigating is the most important aspect of UNDER THE GULF. You have several modes of navigation to select from. The most rudimentary is the MANUAL MODE. Here you can select a course, speed and depth and the computer will do its best to maintain it for an indefinite time. The GOTO-POINT MODE is also a very basic type of navigation. The computer will ask for a specific point, speed and depth and the computer will automatically set your course to that point. Once you are within one mile of the destination position, your speed will be reduced to one knot. Sometimes intelligence information will indicate the detection of an enemy submarine. If so, you may hit the 'S' KEY when the computer asks for the position where you want to travel to. That way, your destination position will automatically be set to that of the enemy submarine. If you ever come across a time when you need to obtain supplies or repair your sub then you can select the SUPPLY-SHIP MODE. This will automatically set your course to intercept the nearest supply ship. Once you are within one mile of the ship, your speed will be reduced and you will automatically surface. Be careful! If you are not paying attention then you might surface in the midst of a battle. There are three modes of navigation which involve monitoring of an enemy target. The first one is the PURSUE-TARGET MODE. When you are in this mode, the computer will automatically pursue a designated target at any speed or depth. The opposite of this mode, where you essentially run away from a target, is the EVADE- TARGET MODE. The TRAIL-TARGET MODE allows you to select a target and then tell the computer to maintain a certain distance away from it. In all of these modes if the computer ever stops projecting the target's position, navigation will revert back to manual on the most recent course, speed and depth. MAXIMUM SPEED and MAXIMUM DEPTH are directly effected by the capacities of the hull and engine. If they are ever damaged then performance will fall. Maximum Speed is also effected by fatigue. If you try to run at the maximum speed for too long, the speed will slowly drop.Points: RADAR/SONAR SYSTEM: RADAR and SONAR are your eyes and ears throughout the game. The radar system works as long as the you depth is less than fifteen feet, any deeper and the sonar system will take over. Both systems can give an immense information about a target. Some of that information is the target's speed, direction, depth, equipment, name and type. To get a complete listing of all information available about a specific target, use the RADAR/SONAR_EVALUATE-TARGET COMMAND. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 10 A A You will be able to see some targets farther away than other targets. This is because some targets will make more "NOISE". You also make "noise" and the enemy's radar range is effected by this. Things that will increase "noise" are speed, weight, radar and sonar power, weapon's status, amount of damage and ship type. Certain things will increase your's or the enemy's "noise" so much that detection is assured. They include launching a long range torpedo, releasing a noise maker, and being struck by a missile or mine. MINES laid by the enemy will be invisible to you until they are detected by your sonar. For this reason it is advisable to use caution when you are operating with very low sonar ranges. No matter your sonar range, you will always see any enemy TORPEDOES fired at you. WEAPONS SYSTEM: The outcome of the game will depend on your careful use of all of your weapons. Using just one system will not result in the most number of enemy ships sunk, you must use each system in conjunction with the others. Each torpedo system has its own advantages and disadvantages. The most obvious is range. LONG-RANGE TORPEDOES out distance SHORT-RANGE TORPEDOES by about two to one. This is due to the nature of the two types of systems. Short range torpedoes are standard torpedoes directed by onboard radar towards their target. They may be slow, but they are almost undetectable during launch. The long range torpedoes are powered by powerful rockets which propel them out of the water and into the air. There, they fly like surface to surface missiles. They are not only fast, but also incredibly noisy. Once they are launched they reveal their originator's exact position. The ACCURACY of the torpedoes is based on the amount of time between the launch time and the time that you last received an exact position fix on the target. Once launched, a torpedo's accuracy will not change. MINES are an all purpose weapon. Use your imagination to put them to use. MINE FIELDS are an obvious thing to make with them, but it is up to you on how you make your fields or where you put them. The enemy also has mines and they are not easily detected when you are operating at high speeds and low sonar power settings. THE ENEMY: The enemy is carefully coordinated. They are not simply individual ships, but instead a team. Communications between them is constant so if one of the enemy sees you then they all will know your coordinates and actions. Their object is to leave the Black Sea and enter into the Mediterranean. However, if they see you, their objective will be to destroy you at all costs. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 11 A A Remember, the enemy can do everything that you can do and they have A COORDINATED EFFORT. There are several TYPES OF ENEMY SHIPS which you will encounter. Here is a short list of the different ship types and their general characteristics. Type: BATTLE SHIP Maximum Speed: 25 knots Best Turn Speed: 14 knots Maximum Number of Torpedoes: 30 Type: CARGO SHIP Maximum Speed: 17 knots Best Turn Speed: 12 knots Maximum Number of Torpedoes: 0 Type: DESTROYER Maximum Speed: 30 knots Best Turn Speed: 9 knots Maximum Number of Torpedoes: 15 Type: FRIGATE Maximum Speed: 33 knots Best Turn Speed: 14 knots Maximum Number of Torpedoes: 30 Type: PATROL BOAT Maximum Speed: 40 knots Best Turn Speed: 22 knots Maximum Number of Torpedoes: 5 Type: SUBMARINE Maximum Speed: 28 knots Best Turn Speed: 12 knots Maximum Depth: 2000 feet Maximum Number of Torpedoes: 25 YOUR SUBMARINE: DAMAGE inflicted on your submarine is automatically fixed over time. If, however, the overall capacity ever goes below 20% then you will SINK. Damage to the hull can cause lead to an uncontrollable DEPTH. The LIFE SUPPORT SYSTEM, when damaged, has reserves for 20 minutes. Once these reserves are gone, the crew will die unless the sub is at the surface. If any system ever has a capacity below 30%, it will not be fixed automatically. The only way for it to be recovered is to rendezvous with your supply ship. You will be informed about any change in the status of your sub in the GENERAL INFORMATION SCREEN. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 12 A A The following are the GENERAL CHARACTERISTICS of your submarine. NAVIGATION: Maximum Speed (submerged): 40 knots Maximum Speed (surfaced): 28 knots Maximum Sustainable Speed: 30 knots Maximum Turn Speed: 17 knots Maximum Depth: 2100 feet WEAPONRY: Long Range Torpedoes Maximum Number: 25 Maximum Speed: 380 knots Maximum Range: 11 nautical miles Short Range Torpedoes Maximum Number: 20 Maximum Speed: 94 knots Maximum Range: 7 nautical miles Maximum Number of Mines: 10 Maximum Number of Noise Makers: 15 RADAR/SONAR: Maximum Radar Range: 58 nautical miles Maximum Sonar Range: 18 nautical miles POINTS SYSTEM: The total number of points which you accumulate will always be displayed on the first line of the screen. When the game begins, you will have 100 free points. Points can be earned by evading in-bound torpedoes (50 points per torpedo), sinking enemy ships (100 points per ship). If an enemy ship every leaves the Black Sea then you will lose 100 points. If you earn a HIGH SCORE then you will be asked to enter your name at the end of the game. The eight highest scores are recorded for future reference and the highest score will be displayed on the opening screen. To view the entire list of high scores, use the OPTIONS_VIEW-HIGH-SCORE command. FILE SUB-SYSTEM: UNDER THE GULF allows you to SAVE and RETRIEVE up to nine different games at once. If the program incurs a DISK ERROR while it is saving then it will automatically abort the save and return to the game. This, however, will not happen if there is an error while retrieving a game. Instead, the program will abort and exit to DOS. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 13 A A AVAILABLE COMMANDS The following is a list of all the commands, which can be selected in UNDER THE GULF, and a complete description of each. The commands will be in uppercase and nested commands will be preceded by the first command you select. Example: COMMAND Weapons_Release-Noise-Maker To select this command you would first select WEAPONS from the main menu. Then from the WEAPONS menu you would select RELEASE-NOISE-MAKER. COMMAND SPEED_NORMAL-SPEED NORMAL-SPEED will make UNDER THE GULF run in real time. This means that one second of play is equal to one second of real time. Real time play should only be used by experienced players who are familiar with all of the commands. Once game play starts, the speed cannot be changed without starting over. COMMAND SPEED_SLOW-SPEED SLOW-SPEED will make UNDER THE GULF run slower than real time. This means that one second of play is equal to two second of real time. Slow play should be used by intermediate or beginning players who are not yet completely familiar with all of the commands. Once game play starts, the speed cannot be changed without starting over. COMMAND SPEED_X-SLOW-SPEED X-SLOW-SPEED will make UNDER THE GULF run very slowly. One second of play will be equal to one four seconds of real time. X-slow play should be used by beginning players who are not familiar with the commands. Once game play starts, the speed cannot be changed without starting over. COMMAND ADVANCE When selected, ADVANCE, will update the enemy and all weapons systems for the entire Turn Time. It is possible to change the Turn Time using the OPTION_CHANGE-TURN-TIME command. ADVANCE, regardless of the Turn Time, will be selected for you when a torpedo is within 5 seconds of your submarine. Once ADVANCE is selected, several screens may appear in the options window which will give general information about the game's progress. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 14 A A COMMAND NAVIGATION NAVIGATION is the one of the most important commands in UNDER THE GULF. Once selected, another menu will appear with various commands dealing with navigation. They include EVADE, GOTO-POINT, MANUAL, PURSUE, SUPPLY- SHIP, and TRAIL- TARGET. The Options Window will also display all information available about navigation. COMMAND NAVIGATION_EVADE-TARGET EVADE-TARGET will automatically set the submarine's course, and continually update it, so that you will be on a heading directly away from a selected target. You can specify any depth and speed at which to evade the target. This is useful if you have suffered significant damage and wish to move out of the weapon's range of a target. COMMAND NAVIGATION_GOTO-POINT GOTO-POINT allows you to designate a point, on the 500nm x 500nm map, for the navigation systems to head to. Depth and speed can be selected manually using this command. If sonar has detected an enemy submarine and you wish to head towards its reported position, you may hit 'S' instead of an X and Y number. Once you are within one nautical mile of the desired point, your speed will be reduced to one knot. COMMAND NAVIGATION_MANUAL MANUAL lets you specify any desired course, depth or speed. If you are pursuing, evading or trailing a target which is no longer being tracked, the navigation systems will revert to manual. COMMAND NAVIGATION_PURSUE-TARGET PURSUE-TARGET will automatically set the submarine's course, and continually update it, so that you will be on a heading directly to a selected target. You can specify any depth and speed at which to pursue the target. This command is useful if you wish to enter a battle with a specific target. Once you are within one nautical mile of the target, you will automatically slow down. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 15 A A COMMAND NAVIGATION_SUPPLY-SHIP SUPPLY-SHIP will set your course to the nearest supply point. Depth and speed can be set manually. Once you are within one nautical mile of the point, your sub will slow down and surface automatically. Be careful when you are surfacing to make sure that there are no hostile targets within weapons range which could fire on you. COMMAND NAVIGATION_TRAIL-TARGET TRAIL-TARGET allows you to specify a target and a distance to trail behind it at. Your speed and course will automatically be adjusted to maintain the specified distance, but your depth can be set manually. COMMAND OTHER OTHER allows you to issue commands that do not directly effect the operation of the ship. The commands available are ABOUT, CHANGE-TURN-TIME, QUIT, VIEW-HIGH-SCORES, RETRIEVE- GAME, and SAVE-GAME. The options window will remain the same when you select the OTHER command. COMMAND OTHER_ABOUT ABOUT will display the version of UNDER THE GULF and other program information in the Options Window. When using this help file, the save game files, and the retrieve game files, they must be of the same version as UNDER THE GULF. The information in the Options Window will remain there until you select another command which needs this window. COMMAND OTHER_CHANGE-TURN-TIME CHANGE-TURN-TIME allows you to change the Turn Time. The Turn Time is the amount of time you are allowed to enter commands and the time for which the enemy and all weapon systems are updated when you select the ADVANCE command or you run out of time. You cannot change the turn time to less time than has already passed. When in-bound torpedoes are present the maximum value for the Turn Time is 30 seconds. COMMAND OTHER_QUIT QUIT simply lets you quit the game and exit to DOS. If you wish to save your game, you must do so before selecting th QUIT command. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 16 A A COMMAND OTHER_VIEW-HIGH-SCORES VIEW-HIGH-SCORES displays the top eight scores in the Options Window. Along with the scores, you can see general information about the game during which the score was earned. If you have a high score, it will be recorded when the game ends. COMMAND OTHER_RETRIEVE-GAME RETRIEVE-GAME allows you to retrieve one of nine games which have been saved on disk, in the current directory. The saved games must have been saved using the same version of UNDER THE GULF. If there is an error in the save game file, the program may be corrupted and forced to abort. COMMAND OTHER_SAVE-GAME SAVE-GAME allows you to save the game you are currently playing. You can save up to nine different games. If there is not enough disk space, or any other I/O error occurs, then you will be informed and the save game operation will abort. COMMAND PAUSE PAUSE stops the game temporarily. You can hit any key after you select PAUSE to resume normal play. In every menu, except NAVIGATION, you can select 'P', even though the command does not appear, to pause the game. COMMAND RADAR/SONAR RADAR/SONAR displays all information pertinent to the Radar and Sonar systems in the options window. You will also be presented with another menu with commands that affect Radar and Sonar operation. They are EVALUATE, FLASH-RADAR (SONAR), OVERALL-STATUS, RADAR, SONAR. COMMAND RADAR/SONAR_DETECTED-MINES RADAR/SONAR_DETECTED-MINES will display a list of all known mines in the Options Window. You can deploy your mines by using the WEAPONS_DEPLOY-MINE command. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 17 A A COMMAND RADAR/SONAR_EVALUATE EVALUATE allows you to see all information known about any one of the targets you are tracking. If a large amount of time has passed since you had direct radar or sonar contact with the specified target, you may be unable to see all of the information. Remember that when you do not have direct contact, the values displayed are only approximations. COMMAND RADAR/SONAR_FLASH-RADAR FLASH-RADAR allows you to momentarily set the radar system to it's maximum power. By doing so, you can locate targets without exposing yourself to any long-term detection. The command on the screen will automatically change to FLASH- SONAR when your submarine dives below fifteen feet. COMMAND RADAR/SONAR_FLASH-SONAR SONAR allows you to momentarily set the sonar system to it's maximum power. By doing so, you can locate targets without exposing yourself to any long- term detection. The command on the screen will automatically change to FLASH-RADAR when your submarine ascends to less than fifteen feet. COMMAND RADAR/SONAR_OVERALL-STATUS OVERALL-STATUS will display the all information about the radar and sonar systems in the Options Window. This command should be used if you are currently evaluating a target and wish to see the general information about the radar and sonar systems instead of the evaluate information. COMMAND RADAR/SONAR_RADAR RADAR lets you select the power at which you wish the radar system to operate at. If the submarine is damaged you may not be able to set the power to 100%. To see the effect that your change made, look at your submarine's radar range which is be displayed in the Options Window. If you choose to set the radar to it's maximum, the computer will automatically increase or decrease power to match the systems capacity. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 18 A A COMMAND RADAR/SONAR_SONAR SONAR lets you select the power at which you wish the radar system to operate at. If the submarine is damaged you may not be able to set the power to 100%. To see the effect that your change made, look at your submarine's sonar range which is be displayed in the Options Window. If you choose to set the radar to it's maximum, the computer will automatically increase or decrease power to match the systems capacity. COMMAND SUB SUB lets you view both statistical and damage information about your submarine. Once selected another menu will appear. By selecting DAMAGE/SUPPLY-REPORT, you will be presented with a window which summarizes all information available about damages and supplies on the submarine. Selecting STATISTICS-REPORT will display information about the progress of the game relative to both you and the enemy. COMMAND SUB_DAMAGE/SUPPLY-REPORT DAMAGE/SUPPLY-REPORT will display all information available concerning damage and supplies. Any damage to a system on the submarine will automatically be fixed over time, unless the capacity of that system has fallen below 30%. All damage can be fixed and supplies replenished by intercepting the supply point at the surface. COMMAND SUB_STATISTICS-REPORT SUB_STATISTICS-REPORT gives a general summary of the progress of the game. The figures given bear no importance to the game's play; however, they may prove to be interesting at the end of a long mission. COMMAND TARGETS TARGETS displays a list of all targets being tracked in the Options Window. Remember that when a target has not been in direct radar or sonar contact for a long period of time, the values displayed are only approximations. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 19 A A COMMAND WEAPONS WEAPONS allows you to fire at your enemy and operate defensive systems to confuse in-bound torpedoes. The Options Window will display all important information that you will need to make decisions concerning the weapon's system. Commands specific to the weapons system will also appear in the menu window. They are LONG-RANGE-LAUNCH, RELEASE-NOISE- MAKER, SHORT-RANGE- LAUNCH, and TARGET-SELECT. COMMAND WEAPONS_DEPLOY-MINE WEAPONS_DEPLOY-MINE will release a mine to the surface behind your sub. Because of your initially close proximity to it, it will not activate for several minutes, but after that it can cause severe damage to both you and the enemy. Mines can only be detected by using sonar, so be careful about running for long periods of time with the sonar turned down. A complete listing of all known mines can be obtained with the RADAR/SONAR_DETECTED-MINES command. COMMAND WEAPONS_LONG-RANGE-LAUNCH LONG-RANGE-LAUNCH allows you fire a long range torpedo at any target within range. Long range torpedoes are rocket propelled and give off a great deal of noise when launched so they will reveal your position to the enemy. These torpedoes have relatively low destructive power. Like other systems, the capacity of the long range torpedo system must be at least 80% to operate properly. COMMAND WEAPONS_RELEASE-NOISE-MAKER RELEASE-NOISE-MAKER allows you to release a noise maker from the submarine. Noise makers will detour inbound torpedoes by reproducing noise similar to the sub's. The farther you travel away from the noise maker, the better chance it has of detouring an in-bound torpedo. This command releases one, which will last for about ten minutes. Like other systems, the capacity of the noise maker system must be at least 80% to operate properly. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 20 A A COMMAND WEAPONS_SHORT-RANGE-LAUNCH SHORT-RANGE-LAUNCH allows you fire a short range torpedo at any target within range. These torpedoes are very quiet and will not reveal your position to the enemy. They also have a huge explosive power compared to long rage torpedoes, but of course their range is limited. Like other systems, the capacity of the short range torpedo system must be at least 80% to operate properly. COMMAND WEAPONS_TARGET-SELECT TARGET-SELECT allows you to get offensive weapons information about a specific target. Once selected, information about the range and accuracy of your weapons will be displayed in the options window. General information about the specified target will also be displayed. Remember that when a target has not been in direct radar or sonar contact for a long period of time, the values displayed are only approximations. COMMAND MAP MAP will display a small map of the playing area in the Options Window. This command is only used when the game is being played on non EGA or non VGA systems. On EGA and VGA systems, you will be able to customize the map which is already displayed in the Map Window. COMMAND MAP_SET-MAP-SCALE This will allow you to select the dimensions of the Tactical Display. Smaller scales are helpful during a battle situation and the larger scales are helpful for navigation. This command is only available on EGA and VGA systems. COMMAND MAP_SET-MAP-SCALE_A)-52_X_27 By selecting this command, the Tactical Display will be set to cover a range of 52 nautical miles by 27 nautical miles. Smaller scales are helpful during a battle situation and the larger scales are helpful for navigation. This command is only available on EGA and VGA systems. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 21 A A COMMAND MAP_SET-MAP-SCALE_B)-70_X_37 By selecting this command, the Tactical Display will be set to cover a range of 70 nautical miles by 37 nautical miles. Smaller scales are helpful during a battle situation and the larger scales are helpful for navigation. This command is only available on EGA and VGA systems. COMMAND MAP_SET-MAP-SCALE_C-103_X_55 By selecting this command, the Tactical Display will be set to cover a range of 103 nautical miles by 55 nautical miles. Smaller scales are helpful during a battle situation and the larger scales are helpful for navigation. This command is only available on EGA and VGA systems. COMMAND MAP_SET-MAP-SCALE_D)-137_X_73 By selecting this command, the Tactical Display will be set to cover a range of 137 nautical miles by 73 nautical miles. Smaller scales are helpful during a battle situation and the larger scales are helpful for navigation. This command is only available on EGA and VGA systems. COMMAND MAP_SET-MAP-SCALE_E)-206_X_110 By selecting this command, the Tactical Display will be set to cover a range of 206 nautical miles by 110 nautical miles. Smaller scales are helpful during a battle situation and the larger scales are helpful for navigation. This command is only available on EGA and VGA systems. COMMAND MAP_SET-MAP-SCALE_F)-412_X_219 By selecting this command, the Tactical Display will be set to cover a range of 412 nautical miles by 219 nautical miles. Smaller scales are helpful during a battle situation and the larger scales are helpful for navigation. This command is only available on EGA and VGA systems. COMMAND MAP_REDRAW-MAP This command will redraw the map in the map window. This is useful because, although information may change, the map will only be updated automatically once every 15 seconds. This command is only available on EGA and VGA systems. A A UNDER THE GULF (c) Matt Kaufman 1 September, 1989 Page 22 A A COMMAND MAP_TARGET-INFO-TOGGLE Circles which indicate your radar / sonar range and you weapons range will constantly appear in the map window. However, the ranges of the enemy will only appear if this command is used to turn them on. The reason why this information is not always displayed is that it can cause a larger scaled map to be very cluttered. This command is only available on EGA and VGA systems.
