About Speen

Swing one circle around the other, plant a leg to switch which ones spinning, and use momentum as your only weapon. Collect glowing pickups to fill your meters, smash through spike balls and rival spinners with a charged leg, and take down a boss bumper to unlock home decoration. Then head into the shared multiplayer world — paint your territory, duel other players, and chase a set of achievements as you go.

How to play Speen

Fill both meters, use charged movement to defeat hazards and rivals, then expand territory in the shared multiplayer world.
