its a pretty awesome game, but i perfered the first one. the start of the third one will probably be surviving on the ship after zombies somehow get on board. spend a few days trying to get to the ships wheel, picking up a few survivors along the way. once there, protect it for a few days, steering to the main-land. once there, you learn the zombieism has already spread.
i like the second but the only flaw is that u can't change gun while shoooting. it changes the mommentum of shooting(not sure if i used the right word...)
