User Summary: This is a sci-fi themed, dual-stick, side-scrolling shmup. You select one of two characters and then "pilot" the character through the levels (there is no ship...just the floating character.) There is an infinite amount of ammo, however the player can also pick up power-ups that enhance the power of the weapons. The game features single-player (story and challenge levels) and local 2-player co-op.
