Tank Battle

Tank Battle is a two-player local browser duel. Two tanks face off on a shared arena. Each player moves up and down and rotates their turret, then fires bouncing shells that ricochet off the walls. Use bank shots and clever angles to land hits your opponent can't dodge. Every hit reduces the enemy tank's HP by 20 — drop it to zero to win the round.

It is built for same-screen play: Player 1 uses WASD plus Space, Player 2 uses the arrow keys plus Enter. The compact controls keep both players competitive on one keyboard, and on-screen touch buttons let two people play on a single tablet or phone. No real-money gambling, no accounts — just instant browser play.

First to destroy the enemy tank wins. Play best-of series with a friend for bragging rights.

Every hit takes 20 HP off a 100 HP tank, so exactly five clean hits end a round. Shells travel at 6.2 units per frame, the fire cooldown is 480 ms, and each shell can ricochet up to six times before it expires — a well-angled bank shot crosses the arena several times looking for a target.

Turret rotation is only 0.05 radians per frame, about 2.9 degrees, which means a 90-degree swing takes roughly half a second. That slow traverse is why pre-aiming beats reacting.
