About Knife.io
Speed and aim decide everything in Knife.io, a fast 2D arena battler where your weapon of choice is a steady supply of throwing knives. You move around the map, line up your shots, and try to take out as many opponents as you can without getting hit yourself. Precise throws matter, but so does staying light on your feet when blades start flying your way.
Matches are short and packed with action, set in vibrant worlds that keep things visually fresh. A large roster of unlockable characters gives you a reason to keep playing after each round. You can go it alone or bring a friend along on the same device in local multiplayer, which makes it a fun pick for quick couch sessions. Players who like arcade action and sharp reflexes will feel right at home.
