Reveal

Your objective, as a member of the Planetary Liberation Force is

to travel to a series of alien worlds, freeing them from the

darkness that has beset them.

At the outset of each level, the world you must free is shown

briefly before it is blacked out. Take careful note of this, as

you will not get another look at the entire level until it is

completed. By travelling over the square sectors that make up

each chequered world you can illuminate it. When all the squares

have been illuminated, the exit square for that level flashes and

must be reached before the time limit expires to teleport to the

next world. Counters at the bottom of the screen display time

remaining and how many squares still need to be revealed to

complete the level.

To make things more difficult, some squares are 'dead ends' and

unlit squares beyond cannot be reached unless an alternative

route is found. Another problem is represented by the marauding

aliens that patrol each level intent on destroying your work.

While patrolling each planet they black out the squares you have

uncovered, making it necessary for you to return and uncover it

again before the level can be completed. If you come into contact

with an enemy a life is lost. Similarly, if you become trapped

on a 'dead end' square, your only alternative is to commit

suicide. As the game progresses, more alien enemies are

introduced and the hidden paths for each level become more

difficult to negotiate. Points are awarded for revealing squares,

with a bonus given upon the completion of each level, and

additional points awarded for time remaining.
