Call of Duty 4: Modern Warfare/Wet Work

This map is based on the Crew Expendable map, it is on a cargo ship and is in the middle of the ocean. Some people find that night-vision goggles help with this map so try them out.

Free for All
This is a fairly enclosed map for this and you will be fired on from every side, pack a shotgun or an SMG if you are planning to run around, an assault rifle with a silencer if you're going to camp for a bit then move on or a sniper rifle if you're going to camp from the upper deck. It is usually best to camp inside on the top deck as barely anyone comes there, you may want to get your pistol out when you go up there in case you see any other campers or alternately you could use Overkill (Perk 2) to get an SMG or assault rifle so you can kill any campers, the other option is just to knife anyone, claymores are also a good choice if you want a warning but barely anyone goes up there because there is usually only one enemy there and it isn't worth it

Team Deathmatch
It is usually best to stick to the corners or snipe from one end of the ship or the bridges. If you are going near corners, take an assault rifle with a silencer and UAV Jammer, the 3x Frag or 3x Special Grenades are a good idea also, just near (not in) a corner for enemies to come and wipe them out.
