In Monsters Rampage you have to kill these bouncing monsters. They split into smaller monsters that you have to shoot again. Upgrade your weapon and complete all 25 challenging levels. You will start with a normal hand gun, if you shoot accurate enough you will be able to get the bigger guns. Do not let them hit you otherwise you need to try the level again. A fun shooting game, have fun!
Use the arrow keys to move, press space to shoot.
