Diep io is a 2D multiplayer tank shooter where you gain levels, spend stat points and branch into very different tank classes. The arena looks basic, but upgrade choices start mattering fast.

How to play

In Diep io you start as a basic tank and earn XP from polygons and defeated opponents. Levels 15, 30 and 45 open new class choices, while stat points improve health, body damage, bullet speed, penetration, reload or movement. There is no magic best Diep io build or best Diep io tank: a sniper setup plays nothing like a drone class. Auto Tank in Diep io is a level 45 option from the basic Tank, with its normal cannon plus an automatic turret. Manager comes from Overseer at level 45, controls drones and can become invisible after you stop using movement keys for a moment. That one rewards patience more than rushing through the middle.

Tips

• Use polygons for safer XP while your tank is still weak
