Blow up the other tank.
Set an angle, set a power, and lob a shell over the ridge. The ground is destructible and the wind is against you. Miss, and it shoots back.
How it works
Angle is how high you point the barrel, power is how hard you hit it. The dotted line shows exactly where the shell will go — buy the Rangefinder and you'll see more of it.
Wind pushes your shell sideways the whole way and changes after every exchange. The arrow shows which way and how hard.
Shells dig craters. Blow the ground out from under a tank and it drops. You don't have to hit dead-on either — a near miss still hurts.
Win and you earn scrap to spend in the depot. The bot gets tougher and more accurate every battle, so keep upgrading.
Damage carries over. Win scrappy and you roll into the next battle still dented — your crew patches some of it up, and the Repair Crew upgrade patches more. Lose and you get a brand new tank, which is the only good thing about losing.
Progress is saved on this device only. Nothing here affects an order.
