About This Game

Build. Blast. Buster.

Robot invaders are marching on your gravity well, and the only thing standing in their way is you, a pile of walls, and a dog who is extremely good at barking. Lay out a maze, plant your towers, hit Send Wave, and watch a very unreasonable number of robots discover physics the hard way.

Your maze is your weapon

Steer the horde through your killzone and give your towers time to work. Leave them a path, though: boxed-in bots will smash the nearest wall or tower to get through. Between waves, inspect, upgrade, repair and rethink before the next attack lands.

Physics does the heavy lifting

Fast-turning Micro Towers, rockets, Pellet and Magma towers, and the mighty Slapper. Knock bots flat, launch them across the map, and enjoy the occasional spectacularly bad landing. No two waves fall the same way.

Fight whoever you want

Upload your own images and put any face on the enemy. Your boss, your brother, busteR. We don't judge.

Campaign, challenges and Endless

Fight from the canyons to the city, the town and out into space. Take on challenge levels, then see how long your layout survives in Endless. Replay missions to earn up to three stars, and chase your saved best stars and Endless wave record.

For Buster

Buster was a real dog and the heart of this game. We lost him, but he's still here in every level, guarding the base. This rebuild is for him: the goodest boy.
