Five battle robots: a purple Strider with a spear, a green Scout, an orange Brawler with a rocket pod, a blue Interceptor with a blade, and a green Tank with a hammer and a cannon

How it plays

1 Assemble

Pick a frame, from the nimble Strider to the hulking Tank, then bolt on blasters, blades, hammers, rocket pods, railguns, armour and gadgets. Every part changes how heavy, fast and tough it is.

2 Give it a brain

Start from a ready-made fighting style, or write its tactics yourself: when a shot is coming, sidestep; when health is low, back off. Your robot fights on its own with the brain you gave it.

3 Battle

Queue up and watch the fight play out in 3D against another player's robot. Win coins and trophies, buy better parts, tune its tactics, and climb the ranks.

A duel in the arena: an orange Brawler and a blue Interceptor trading fire — Every fight plays out in 3D

The Garage: a robot on its stand beside its loadout of parts — The Garage: fit parts, paint it

The Brain: a list of tactics, each a condition and an action — The Brain: plan its tactics
