How to Survive: Storm Warning Edition

After you get to Kovac's island, he tells you need to head to a secure hut to rest. You head out with a shotgun you just made. When you open the gate to the shack zombies come swarming at you, just let 'em have it with the shotty. One thing I did to make it easier is run away so a bunch follow me, then just turn around and kill 'em.

Early in the game, you are able to make a fire pit. GEt a stick, light it on fire, and burn a bunch of zombies that are in a cluster.
