Take charge of a giant robotic snake and smash through cities with ease as you fight to create the most fearsome weapon of all time. Your objective is to destroy everything!

The key to victory lies in building Colossatron by attaching coloured Powercores as they appear. Different colours and unlockable gadgets can be combined to form bigger, badder weapons and stronger Powercores, with thousands of potential combinations.
