Kill the dead ahead on a motorcycle. They are zombies, walking and searching for brains. Shoot the followers and knock down the monsters in front. Use the WASD to move or the Arrow keys, knowing right arrow and D are for increasing speed. That's the best way to knock down the dead ahead, yet it's also more dangerous to drive the motorbike that way. Crash onto anything heavier than a zombie and the player will fall to its death. Don't let him turn into zombie dinner, using Space-bar to shoot with his gun and collecting the bonuses along the way.
