Diep.io

"Diep.io" is a browser shooter where you control a single tank on a vector field and shoot at geometric shapes. The main feature here is the class tree: as you gain experience, the tank changes shape, evolving from a basic circle into a sniper, a destroyer, or a machine gun. This build mechanic differentiates the game from simple io-arcades where only the skin changes.

You use WASD or arrow keys to move across the map, while the mouse aims and shoots with the left button. The gameplay revolves around destroying yellow squares, red triangles, and pentagons to earn points and level up. In the upgrades menu you decide where to spend points: into movement speed, bullet speed, bullet penetration, or max health. The game sets no global mission, you simply exist on the map, upgrading stats and watching your cannon change.

Fans of minimalist graphics and meditative character grinding without complex plots will enjoy this. It is perfect for killing half an hour in a browser, constantly improving your stats. Tip: do not engage other tanks in the first minute, fully upgrade bullet damage and health regeneration first. If you wander into a corner of the map without penetration upgrades, local players will destroy you quickly.
