The bike allows you to run through any obstacle or zombie, making you virtually invincible. You can also tap and shoot with unlimited ammunition.
Boosts
Always try to collect boosts, such as ammunition, the flamethrower, the bike for an easy way to score more points.
Coins
Spend your coins on leveling up your character as soon as you have enough. New characters will be automatically unlocked, and all previously earned bonuses will also be applied to the new characters.
Conserve ammunition
Ammunition can only refilled by collecting ammo boxes during your run. Do not waste it by shooting every zombie that is encountered. Focus on your main goal, which is to run as far as possible to earn points and coins. Choose safe routes where you do not have to fire a single shot. Squeeze through zombies and obstacles and save ammunition for when it is absolutely required. The safest route is the one also results in the most points. There will be areas where buses will come towards you. Try to look ahead and notice them from a distance to make it easier to choose the safe route. You can hit some obstacles, including zombies, one time without triggering a game over. To get farther and conserve ammo, do not be afraid to hit the occasional zombie.
Flamethrower
Remain in the center after collecting the flamethrower. When exploding barrels appear, this will give you an opportunity to easily eliminate all zombies. Scout the entire area because one zombie will drop an ammo box that should be collected.
