Are demolition derbies your thing? In DeathCar.io, you'll play against other cars- your only main objective is to literally smash your opponents. Rev up your engine, demolish your opponents, and be the king of the road.
Mouse: direct your car
Left click: boost your car
Right click: apply brakes
You have a map of all of the other players on the board- use this to know when it's safe to take a quick break from the action to recharge. Also, stay away from the walls. Anything you hit hurts you, so don't waste your precious life on a non-player!
