Charlieís Games has unveiled a new arcade-style shooting game for the Mac platform, Irukandji. Taking place in an abstract underwater trench, players control a well-equipped gun ship and try to eliminate hundreds of animated sea monsters that do everything from kamikaze to shooting at the player. The object of the game is to force your ships way to the final confrontation, a giant translucent crab, defeat the monster, and gather as many points as possible along the way by killing enemies and avoiding death.
