Ninja.io

Fight as a physics-driven ninja in 2D multiplayer arenas stocked with varied weapons. Every jump, shot, and collision follows real momentum, so no two eliminations play the same.

Choose Deathmatch and race to the kill limit, or play Capture the Flag and return three enemy flags to win. Register an account to track achievements across sessions.

Maps rotate often enough to keep movement fresh. Press H in-game to view control details when you need a quick reminder.
