Set the zombies ablaze with your traps. Try to fire them when the zombies are over the center of the traps. If you fire it when a zombie is not over the trap, you will lose fuel. If a zombie makes it past the trap, your barricade will be damaged. The round ends if the zombies cause too much damage to your barricade or you use up all of your fuel. Use the Q, W, E, R or T keys to prepare your traps and press space bar to fire them. Press the ALT key to use your righteous bar when full. Press the TAB key to feed your sessions points to the righteous bar.
