This is a liberated game: it was originally shareware, but in December 2005 Apogee Software released the full version as freeware.
Try out some of the secret weapon attacks hidden in the game:
Super Plasma Bolt: Hold the up arrow until you hear a charge sound, then press the fire key.
Fireball Attack: Turn left and right 6 or 7 times in a row, then press the fire key.
Electron Shield: Turn left and right 6 or 7 times in a row, then press the jump key.
Invincibility Burst: Hold the up arrow until you hear a charge sound, then press the down arrow key.
Full weapons: Press the following three keys together during gameplay: C-A-T. You will receive the machine gun, 99 ammo and 99 grenades. Note that this only works in the registered version!
