MooMoo, Slither, Agar, Brutes, Lordz, ... The list of multiplayer .io games is becoming longer and longer! Diep.io is a new addition in which you control a tank and shoot down both opponents and obstacles. This lets you upgrade your tank while you try to survive as long as possible.
Diep.io is made by Matheus Valadares, the same developer as Agar.io.
Diep.io is available as a web browser game (using HTML5), as an Android app, and as an iOS app.
Use WASD to move your tank around, and your mouse to aim and shoot.
