Brian Damage: Infinite Slaughter - Earth is being overrun by monsters… again. Time to dust off the military-grade weapons and send those monsters back to hell. You know the drill. Kill all the monsters – you’ll get a flashing arrow when you can move on! At the end of each level you’ll face a bigger monster – kill that and then head to the exit with this arrow. Arrow keys to move, mouse to aim and shoot and 1-6 keys to choose a weapon.
