Matt and Draconica's Surf shack is under attack by zombies. The two head off to defend it, with the assistance of a friend - Tidal. He made a barrier next to the Shack to keep the zombies away. Though it does disappear if it's pushed by zombies too much. Sometimes it'll attack and throw zombies back. If any zombies cross over the barrier, or once the barrier is gone, Tidal will kill any zombies that come too close. However, a fair chunk of your score is lost. Your task is to kill as many zombies as you can in the given time. You're able to use abilities from all 3 characters. DON'T FORGET to go through the Tutorial Section in the game to learn about the different characters and their strengths. The main character you control is Matt, who is at the front.
