The game consists of several rounds, divided into 10 stages.

There are two ways to clear the stage. One is to wipe out all enemy androids on the playfield. All player characters will be usable in the next stage. The other way is to lead all player characters safely out the EXIT before the time expires. If the time expires, all characters that have not exited, including the one currently in use, will be lost. Only the characters safely out the EXIT are available for the next stage.

The game will be over if you lose all player characters. If you have credits left in the game, press to continue. Note that the game cannot be continued if you have reached Round 5.
