Pick one of 8 tanks. Each has its own weapon: Cannonball, Double-Shot, Poison Dart, Mine Layer, Poison Cloud, Shock, Homing and Drill.
It's turn-based. On your turn, drive left or right (this uses fuel), aim up or down, then hold FIRE to charge your shot and let go to shoot. The longer you hold, the stronger the shot. You have 15 seconds per turn. Your last shot's path and power stay on screen to help you adjust.
Watch the wind arrow at the top. It pushes every shot a little and moves poison clouds a lot.
The ground breaks apart. If the ground under a tank is blown away, the tank falls to the platform below. If there's nothing below, it falls off the map and is out.
At the start of every round, pick 1 of 3 power-ups, like more damage, thicker armour, critical hits, extra turns or a chance to come back to life. Your tank is fully repaired between rounds. Each round brings more enemies, and they aim better.
Scoring: points for every enemy tank destroyed and a bonus for surviving each round.
On a keyboard: A / D or ← → to drive, W / S or ↑ ↓ to aim, hold Space to charge and fire, P to pause, M to mute, Z to zoom out (small screens) and 1–3 to pick a power-up. On a phone, use the buttons, or drag from your tank to aim.
