1. Gameplay/controls: You have to drive a car and kill monsters on your way. There is a tutorial on how to play. At the top left corner your coins and ammo are displayed. At the top right corner is a pause button. There are pedals on your left and right to control a vehicle and a fuel indicator between. Tap the screen where you want your gun to shoot. 2. Earning coins: Coins may be picked up on missions or bought from the store. You can also collect coins by watching videos (ads) that appear from time to time. 3. In-app purchases: We have recently added an in-app store. There you are offered to buy various goods (for instanse vehicles, saws, ammo packs etc.) as for coins, so for gems. There you can also donate (buy gems for real money). 4. Updates: The game was released recently and updates are arriving shortly. They may contain fixes, new missions, store upgrades etc.
