Play as Robbie the tank robot, prototype #36. Initially designed to create helpful monsters with its experimental missiles, something clearly went wrong because the monsters are not helpful at all and in fact quite unfriendly! With the recent budget cuts, the lab is unable to stop the test sequence, so Robbie will have to fight off as many monsters as they can! This is a unique twin-stick arena shooter where your own actions define the difficulty. Shoot recklessly at the walls and you will drown in enemies, but shoot too little and you will have a mediocre score. Unlock and play in 6 different arenas with their unique monsters, and compete in seeded daily challenges which keep throwing new sets of monsters at you until you die, solo or in co-op!
