In the beginning of the map you will land your boats are on the beach, you and you team mates are defending a series of trenches and bunkers. You have at your arsenal, bouncing betties, mounted machine guns, deployable weapons, mortars and a few custom weapons that will be sure to blow your mind.
From the trenches you make you way trough a series of mountain side bunkers again with lots of twists and turns. There is a last stand area that will blow your mind.
Now back to the AI, you have reinforcements, that you can gain from time to time to help with the onslaught of zombie attackers. There is also the presence of enemy AI who has a large arsenal of weapons also.
There is also times that all 32 zombies will spawn at one time, and it will truly make you crap your pants, as it will feel as if it is too much to handle.
