Strategy
Humans
Once you spawn in, grab anything you need quickly, as the zombies can get easy kills from behind at a nearby spawn point. Leave the spawn are and head down into the ship.
Take a look in the room directly in front of you as you enter, as it has barricade hammers, meds, and a primary weapon usually. The door on the left also may have zombies and they could also be in the room.
If you finish all the objectives before the escape, use the two boats, and the zombies will never get you.
Zombies
At start, make good use of the spawn, as it is very close to the humans.
It's dark in some parts of the ship, like the pump room. Use it to an advantage.
On the fourth objective, if it's being completed, run to stop the advance without losing the spawns.
The ship is full of dark passages that are connected, attack very closely to get some humans (with hordes or an ambush).
