Setting the survivors free

Once you open to the room where the 3rd 115 meteorite is you'll find a door steel door. When you knife it you'll here the voices of the four characters from the old game, Takio, Dempsey, Nikolai, and Richtofen. Mostly they are complaining how there's no power and hear them ask you to find a fuse.

Once their done talking head up stairs in the same room to find an old fashioned tube fuse on the desk next to the meteorite. Once you've picked it up you can use it on the panel to restore power for the survivors, and they'll give you the next couple of instructions which involve destroying "4 half mooned generators" on the map.

the first one is directly behind the door in the same room and will start glowing red. You can either use the scavenger, frags, or, semtex to blow it up. (cross bow or other launches might work as well) The second generator can be found in the water in between the two bridged walkways coming from the cracked haul of the ship. The third on the port side of the ship past the claymore room. The fourth and final generator can be found behind the stamin-up garage just out side the back window.

Once these have been destroyed you can return to the door for more instructions to find they want some vodka. The vodka supposedly spawns in one of three spots usually on the ship. It will be incased in ice on a railing where one player may knife it to set it free while the second must stand on the lower deck to catch it. (if it's dropped it should respawn in another location) Once the bottle is acquired return to the door to place it in the drive through bank window looking vacuum shoot to receive the next set of instructions.

The next step is said to be the last but has yet to be posted. They apparently ask for a "golden rod" location unknown, but once this step is completed it should set them free and unlock an achievement.
