One iPhone. Two players. Instant rivalry.

Achtung Duo turns any spare moment into a pocket-sized battle arena. It is fast, easy to pick up, and impossible to put down. Steer your snake, dodge danger, cut off your rival, and outlast everyone else in quick, chaotic duels.

Created in 2010 and played millions of times worldwide, Achtung became a cult favorite for fast local multiplayer. Now Duo is back with its biggest update yet, rebuilt for modern iPhone.
