Harlequins and undead will engage in violent conflicts in the Zombie Clash 3D: Halloween shooter, set in a deserted amusement park. To earn points, your team must track down and kill zombies. You can also earn points by locating the scarecrow and bringing it back to your headquarters. Another goal is to try to stay alive for as long as possible to prevent the other team from scoring. A match lasts for three minutes and thirty seconds, and the team with the most points at the end of that time is the winner. Your main weapon will be a shotgun, but the map also contains a crossbow, which is better at long range, as well as many bonuses that increase your speed or health recovery. You will get stars for each game you complete. You can use these stars to upgrade your character's traits or buy cosmetics from the store.
