When you start, half of the players buy an M14 (500) and the other half buy an Olympia (500).

Then when George A Romero comes, do not shoot him. Then when you have earned about 2500, one of you clear the debris to the right (750).

Then all of you buy an MPL. Then go to the back of the ship and camp there for a while. This should serve as a good tactic for a while.

When you have earned about 4500, go buy the next debris (costs 1000). Then camp up there and guard the stairs and the barrier inside.

Then run upstairs and turn on the power. Camp around that area and use the zipline if you have to.

Also go buy ammo if you need it and use Pack-a Punch if the player wants it.
