Enter the vibrant and chaotic arena of Diep.io, a top-down multiplayer shooter that has captivated millions. You start as a simple, small tank in a vast field filled with geometric shapes. Your primary goal is to survive and grow stronger by collecting experience points from destroyed shapes and enemy tanks. As you level up, you unlock skill points to invest in seven core attributes: health regeneration, maximum health, body damage, bullet speed, bullet penetration, bullet damage, and reload speed. The true depth of the game lies in its branching upgrade system. Upon reaching certain levels, you can choose to evolve your tank into specialized classes like the rapid-firing Twin, the defensive Tri-Angle, the sniper-focused Ranger, or the area-controlling Overseer. Each class offers a distinct playstyle, encouraging strategic experimentation. The game features multiple modes, including Free For All, Team Deathmatch, and Survival, where you must outlast waves of increasingly powerful enemies. With its simple controls, deep progression, and intense real-time PvP combat, Diep.io offers endless hours of strategic tank warfare.
Use your mouse to aim and the left mouse button to fire your tank cannon. Use the WASD or arrow keys to move your tank around the arena.
Destroy the multicolored geometric shapes scattered around the map to gain experience points (XP) and level up. Each level grants you a skill point.
Press the upgrade button (or the B key) to open the upgrade menu. Spend your skill points to improve your tank stats or evolve into a more powerful tank class. In Diep.io, choosing the right upgrades is key to dominating the battlefield.
In the early levels, focus on farming geometric shapes in safe areas of the map to level up quickly before engaging other players.
Do not neglect your movement speed and health regeneration stats. Survivability is often more important than pure damage output.
Learn the strengths and weaknesses of each tank class. For example, fast "rammer" builds are strong against slow, bullet-spamming tanks but weak against snipers.
In team modes, stick with your allies. A coordinated group of tanks is much more powerful than a lone player, even at a high level.
Use the environment to your advantage. You can hide behind the indestructible pentagons or squares to block incoming fire and regenerate health.
For players new to Diep.io, a balanced build is often the best starting point. Invest points evenly across several stats instead of maxing out just one or two.
The upgrade system is genius. I love how you can build your tank for speed, damage, or defense. Finding the perfect build for each mode is so satisfying.
Best .io game out there. The class variety means no two matches are the same. The Ranger class is my favorite for picking off enemies from a distance.
Incredibly fun and competitive. The only reason it is not a perfect 5 is that sometimes you can get overwhelmed by high-level players early on. It is a great challenge though.
More than just a shooter. You have to manage your upgrades, position carefully, and choose your fights. This game has surprising strategic depth for a browser title.
Perfect game for quick sessions. The progression from a weak tank to a powerhouse feels amazing. Team modes are especially chaotic and fun.
I have been playing for years and I still come back. The developer did a fantastic job balancing the different tank classes. Mastering the Overlord is my ultimate goal.
Simple concept executed perfectly. The moment you evolve into a new tank class for the first time is pure gaming magic. Highly recommended for anyone who likes action games.
Easy to pick up, hard to put down. It is a great stress-reliever. I just wish there were a few more maps to keep things fresh.
The fastest way to level up is to destroy the larger shapes, like pentagons and triangles, as they give more experience. However, they are tougher to destroy. A safe strategy is to farm smaller squares and triangles in less crowded areas at the start.
There is no single "best" tank in Diep.io, as it depends on your playstyle and the game mode. The Overlord is excellent for controlling areas with drones, the Fighter is great for hit-and-run attacks, and the Destroyer can one-shot opponents with its massive bullet. Experiment to find what suits you.
The color indicates the shape type and experience value. Brown squares are the most common and give little XP. Green triangles give more. Large blue pentagons give a significant amount of XP and are often contested. The rare pink "alpha" pentagons give the most experience but are very dangerous.
While there is no direct "friend invite" system, you can coordinate to join the same server in a specific region and game mode. You can then find each other on the map and team up informally in Free For All or play together officially in Team Deathmatch.
When your tank is destroyed, you lose all your levels, upgrades, and score. You will respawn as a basic Level 1 tank and must start your progression again from the beginning of that match.
In Team Deathmatch (often labeled as 2-Team or 4-Team mode), players are automatically assigned to a colored team (e.g., Red, Blue). You can only damage players on the opposing teams. The team with the highest total score when the timer runs out wins.
Arena Closers are giant, indestructible pink tanks that spawn in the center of the map when a player reaches the maximum level (45) in a Free For All game. Their purpose is to end the match by destroying all remaining players, declaring the top-level player the winner.
No, there is no way to reset your skill point allocation during a match in Diep.io. You must plan your build carefully. If you are unhappy with your build, you will need to die and start over with a new strategy.
Survival mode pits you against AI-controlled "fallen" tanks instead of other players. These tanks are aggressive and will hunt you down. The goal is to survive as long as possible against increasingly difficult waves of enemies.
The name Diep.io is a combination of "diep," which is likely a reference to the depth of its upgrade system and tank classes, and the ".io" domain suffix popularized by simple, multiplayer browser games like Agar.io.
