The Supply Depot

Each raid begins with a visit to the Supply Depot.  Here you can purchase ammunition for your weapons, acquire additional weapons and fortifications,  upgrade your ammunition and guidance packages, and make special acquisitions to aid your defense.

As you move the mouse pointer over various items in the Supply Depot screen, watch the upper-right of the Depot screen for information on the cost of the item under the pointer.  Clicking on an item displayed in GREEN text will purchase it (if you have sufficient supplies).  Guns you have already purchased are displayed in GREY.  The currently-selected gun (which will be active at the start of the next raid) is displayed in YELLOW.  To change the current selection, simply click on one of the alternative choices.  You won't lose the previously-selected weapon by choosing another.

Ammunition is displayed as a fraction with the numerator the number of shots currently available and the denominator the maximum number of shots the gun magazine can accomodate.  To buy ammunition, click on the '+' sign near the ammunition indicator.  Hold the Option key down while clicking to buy 5 rounds at a time.  Hold the Command key down while clicking to buy sufficient ammo to fill the magazine (if you have sufficient funds, of course).  To sell back ammunition, use the same procedure but click on the '-' sign.

Specials (Camouflage, Speed Shot, and Ammo Cap) are purchased in similar fashion.  The Speed Shot improvement is bought on a per-shot basis just like ammunition.  Extra Ammo Capacity is bought for all weaons simultaneously.  There are three camouflage nets that are purchased separately.  The 'L' and 'R' nets protect your ground defense emplacements, while the 'C' net covers your gun.

If you want to abort your purchasing decisions and begin again, press the Revert button at the bottom right of the Depot screen.  This will restore the conditions when you arrived at the Depot. 

When you are ready to proceed to your gun emplacement and begin the next raid, press the Man Defenses button.
