Instead of stowing each 1UP you collect, each new ship becomes playable immediately, resulting in an ever-growing armada of destruction!
With your home world ruined, lead your detached battalion's charge by destroying the mechanical-tentacle hybrid attack forces responsible for your pain.

• Sacrifice ships for a BULLET-VAPORIZING BOMB which increases in power the more ships you've collected!
• Hardcore? Crank up the difficulty and gameplay speed for THUMB-TWISTING maneuvers!
• Classic shmup design - 8 levels of alien-fighting action, ready for you to get your revenge!
