Drive a tank around an arena, shoot crystals for XP, level up, pick upgrades and a turret, and outgun computer rivals.
Move with W, A, S and D or the arrow keys, aim with the mouse, and hold the mouse button or Space to fire. E turns auto-fire on or off. When you have upgrade points, press 1 to 6 to upgrade Armor, Repair, Engine, Reload, Caliber or Velocity; at level 10, press 1, 2 or 3 to pick a turret. P pauses and resumes. M turns sound on or off. F switches full screen. On a touch screen, drag on the left half of the arena to drive and on the right half to aim and fire, and tap the upgrade buttons.
Tank Brawl is an io-style tank shooter. You roll into a large arena scattered with floating crystals and computer-controlled rival tanks. Shoot crystals to earn XP, level up, and spend upgrade points to turn your little tank into a fortress, a speedster or a sniper.
At level 10 you pick a new turret, and the fights get serious: knock out rival tanks for a big share of their XP before they do the same to you. It is single-player and runs in your browser on desktop and mobile.
| Drive | W, A, S, D or the arrow keys |
|---|---|
| Aim and fire | Move the mouse; hold the left button or Space |
| Auto-fire on or off | E |
| Upgrade a stat | 1 to 6 (or click it) |
| Pick a turret at level 10 | 1, 2 or 3 (or click it) |
| Start or play again | Enter |
| Pause and resume | P (Esc also pauses) |
| Full screen | F |
| Sound on or off | M |
| Drive | Drag on the left half of the arena |
|---|---|
| Aim and fire | Drag on the right half; you fire while you hold |
| Upgrade | Tap a stat or a turret at the bottom of the arena |
| Pause and resume | Pause button in the top corner |
Crystals drift slowly around the arena. Small blue shards give 10 XP, amber prisms 25 XP, and big purple cores 120 XP but take many more hits. A broken crystal is soon replaced somewhere else. Ramming a crystal also wears it down, and scratches your tank a little.
Your score is your XP. Levels come faster at first and slower later, up to level 30. Higher levels mean a slightly bigger, tougher and slower tank.
Every level brings one upgrade point. Spend it on Armor (more health), Repair (faster healing), Engine (speed), Reload (fire rate), Caliber (shell damage) or Velocity (shell speed and range). Each stat goes up to 7, and you will not have enough points for everything, so choose a style.
At level 10 you swap the cannon for one of three turrets: Gatling (sprays fast, light shells.), Longshot (slow to reload, hits hard from far away, and sees further.) or Triple (three barrels fire a fan of shells.).
Shells damage the first tank or crystal they hit, and your own shells never hurt you. Tanks that touch push each other apart and both take damage.
Knocking out a tank earns you 40% of its XP plus 25. Tanks repair slowly all the time, and much faster after 5 seconds without being hit. A new tank is shielded for 2.5 seconds.
Every other tank is controlled by the computer and marked AI on the arena leaderboard. Chill has 6 rivals that mostly farm crystals and aim loosely. Normal has 9 that fight when they are winning and back off when hurt. Fierce has 12 that lead their shots and press every fight.
Rivals join at different levels, so some are already strong. A rival that is knocked out is replaced a few seconds later.
Your result is the XP you reached in the round. The best result for each rival level is saved in this browser.
No. Tank Brawl is single-player. Every other tank is a computer-controlled rival, marked AI on the leaderboard, and nothing is sent over the network while you play.
Yes. It is free to play in your browser with no account, download or payment.
When you level up, upgrade buttons appear at the bottom of the arena. Press 1 to 6 or tap a stat. At level 10 you pick a turret first, with 1, 2 or 3.
Yes. Drag on the left half of the arena to drive and on the right half to aim and fire. The game pauses automatically if you switch apps or tabs.
Your best XP for each rival level is stored in this browser on this device. It is not uploaded or shared, and there is no online leaderboard.

Start as a tiny blob in a big arena: eat pellets, swallow smaller rivals, split to lunge at prey and dodge anything bigger than you.

Draw loops out of your land to claim the arena square by square, cut through rivals’ trails and guard your own.

Grow a glowing snake in an arena full of computer rivals: eat orbs, boost past danger, and make rivals crash into your body.
