INSTRUCTIONS FOR PLAYING CHERNOBYL
Source Code is Turbo Pascal 3.0
This is a game in which you try and neutralize radiation that has leaked
into a reactor containment building. Neutralization occurs when the
atomic particles are trapped with a magnetic force field laid out by
a robot ionizer under your control. See below:
┌────────────────────────────────────────────┐
│ Force field line │
│ / │
├───────────┐ │
│░/░░░░░░░░░│ Radiation in unfilled │
Radiation in │░░░░░░░░░░░│ / area is not destroyed │
filled area │░░░░░░░░░░░│< and will bounce off │
is destroyed │░░░░░░░░░░░│ \ any filled areas. │
│░░░░░░░\░░░│ │
└───────────┴────────────────────────────────┘
Areas sealed off by the ionizer gain you points proportional to their area,
full points are given to areas created at slow speed (filled red) and half
points to areas created at fast speed (filled yellow). A decreasing time bonus
is added to the area score on completion of each frame. This frame score is
then multiplied by a frame difficulty factor, and the product added to the
total game score.
The force field must be laid out from an existing line of force and must
join back to an existing line of force in a closed circuit. Typical examples
are shown in the following diagram :
┌────────────────────────────────────────────┐
│ 2 Line 1 to 2 forms │
│ a closed circuit │
│ │ between parts of │
│ │ the outer frame. │
│ │ 3 │
│ ├────────┐ Line 3 to 4 forms │
│ │ ──────┘ a closed circuit │
│ 1 │ 4 from line 1 - 2. │
└──────────┴─────────────────────────────────┘
SOUNDS TOO EASY ?
If you think this sound too easy your ionizer will be destroyed in any of the
following circumstances:
a) The ionizer or its uncompleted trail is hit by radiation before
completing the circuit.
b) The ionizer is hit at any time by one of the robot guards running
amok in the plant.
c) The ionizer is short circuited onto a trail it is still drawing out.
If you still think it sounds too easy just try it !!
MOVING
The ionizer can only be moved left ,right, up and down. The moves are made
with the A, S, semi-colon (;) and full-stop (.) keys respectively. It is
better to hold down the keys to make a move rather than to stab at them
repeatedly. You may move along the outer frame and any previously drawn force
lines at any time
BUT TO START DRAWING A NEW SHAPE YOU MUST PRESS THE SPACE BAR FIRST.
Upon pressing the space bar a tone will be heard to signify that you are now
vulnerable. If you later decide not to start a new line, simply move along an
existing one instead to cancel the effect of the space bar. Before or during a
new shape move you may press the space bar again. This will engage high speed
and a higher pitch tone will be heard. Once high speed is selected during a
move it cannot be cancelled until the move is completed.
Key H will suspend the game until a further key is pressed.
STRATEGY
Early on when radiation is low and guards are few it is best to go for a quick
kill. This maximizes the time bonus and minimizes the risk. Timing is
paramount a typical example as below:
┌────────────────────────────────────────────┐
│ 3 C │
│ / \ │ 1 │
│ / \ / │
│ / \ / │
│ └─ │B \ / │
│ 4 │ \ / │
│ │ \ / │
│ │A \2 / │
└──────────────────┴────────────────────────┘
As the radiation travels from 1 to 2 and on to 3 draw from A to B, wait for the
radiation to pass and then complete the circuit at C, thus trapping the
radiation in the left hand side.
Later, the best strategy is to draw a finger in stages at fast speed,wait for a
reasonable amount of radiation to enter the entrapment area and then complete
the shape preferably at slow speed to maximize points. Diversionary lines can
be draw elsewhere to draw the guards attention. See below for a typical
example.
┌────────────────────────────────────────────┐

As mentioned by the terminal message an enhanced version of the game can
be obtained by sending US$15 to my wife: Virginia Doré, PO Box 70371,
