Watch the cool boarding of the ship and then you get to have fun sniping guys in the heads again. Listen to the people talk and then decide where you want to go. Some people have found that you can break into the bridge without the key. I'm going to walk you through the way with the key just to be safe. Wait for the 1 guard to walk off and then shoot both of them, and take their uzi's. Now enter the doorway on the left. (it has a radio and stairway symbol by it. And go inside. Once you see the stairs head to the left and then down that corridor to the first right. Go down the stairs here. Head out the doorway to your left and hang a right down the hallway. The first door on the left has a uzi in it, and the first door on the right has a man sleeping in it. Open this door and kill him, take his uzi and grab the keycard on the desk. Note the Doom game being played on the computer ^_^. Now head back up the stairs, go up the second set of stairs, and turn around at the top. There is a doorway leading back outside which you want to go through here. After getting back outside head left and up the stairs to the top of the ship. See the doorway with the scanner on it? USE your keycard on it and your obj will update. Head inside the bridge now. Walk past the radio room door and shoot the guy on the bridge in the head, and grab all the ammo in this room. Now head back to the radio room door and pick it open. Watch out for the guard in this room, sometimes he's patrolling and other times he is in the next room looking out the window. Head down the stairs and go into the door on your right. Hit the switch in this room and your obj will update. Now you have to go remove the container from on top of the bay doors. Head back out the doorway and go out the portal/door on your right. The crane is way far in the distance at the front of the ship. The easiest way down is to jump over the railing, land on the shipping containers and then sneak forwards along the left side. Shoot the guard down there once he stops and then jump down. Go forwards until your standing over the cargo bay doors, and then head to the right hand side of the ship. Sneak forwards, take out the 1 guard, and then goto the crane. If you need armor, go in the little hole behind the crane. Otherwise active it. Once you start the crane a few men will come back from the way you came (now the left side of you. Go to your right and hide behind the box's there. Jump up on top of the box's and you will be able to get to the other side (where the container you just lifted is. Now sneak your way back to the radio room (2 new guards) and hit the switch to open the bay doors. Watch out for the new guards on the way back to the Radio room. Now take the same route you did the first time, going to the crane, and instead this time go to where the cargo bay doors and are jump down into it. Jump in the hole in the upper left corner of the packages to end the level.

Notice something different? No alarm! Time to break out the bigger guns. Proceed forwards on the walkway and through the doorway at the end of it. Go forwards through the next section of the cargo bay and jump over the railing and down between the shipping containers. Head forwards into the next compartment. Now run all the way forwards, kill the guard on the overhead walkway (hard to see) and head left. Jump down to where there is a small lifter and activate it (USE). Now jump up the box's to the left of the lifter and you can now jump onto the newly raised box's so that you can jump onto the catwalk. Go down the catwalk and head through the open door. If you want shoot the guys through the glass, but I find it's easier to run inside with the shotgun. After clearing this room, next through the far side. Grab the health's if you need it and proceed through the door. Kill the 5 guards in this room and then head down the stairway. Use the walkway at the bottom to go over the engine and then exit through the far doorway. Go through this hallway and into the next engine room. Kill the all guards and then exit through the doorway to your left, hang a left from here and go down a ladder into the bottom of the engine room. Head down the long corridor and turn the wheel at the end (Shuts off the flames) Now go all the way back to the ladder but head right instead. You have to run past the steam, I usually stick to the far left and only take a little damage, but I heard you can crawl under it to take no damage. Go down and through the next doorway to get your obj updated. Now you get to destroy the ship instead… more things blowing up! Work your way through the biohazard containers until you come to a ladder leading down. Take it down and head to your right (only way you can go) Go through the first door there and down the ladder to set the first charge (USE key) Now go back up and head to your right. Head in the door the guard just came out of and down the ladder by the blinking red light to set the second charge. (There are 2 small health kits up here) You can crouch to get under the steam vent. Now go through the door on the opposite side of the room (past the equipment) and kill the guy hiding to the right. There is a armor and ammo by him. Then head down the corridor. Head to the right and through the doorway. Loop around and through the next 2 doors. In the room with the big generator is a large health kit and to the right after you exit that room is the ladder leading to the third charge. Once back up the ladder, head down the corridor and to the left to find the forth bomb site. Now go back up the ladder, to the left around the box's (kill the 2 guards there) and go forwards until you go through a doorway and have to go up another ladder. Open the doorway and prepare to fight among all the canisters. Once you go out the door, hang a hard left and go back that way, kill the 4 guards, and hang to the right path. When you see a, well lit, flat place of box's jump up on to of it and head right. When you jump back down, if you turn to your right you should see another doorway. Go in this and down the ladder in there. Go right out the doorway around the corridor and then through the first doorway on the left. Kill the 2 guards and then go down and plant the fifth explosive.

Cut-scene, with cool boom.

The Armory Mission briefing: standard stuff here. Walk over to the buzzer on the door and ring twice. Watch the cut-scene and follow Sam. Try not to get in the NPC's path… although it's funny hearing Sam yell "Go AWAY!!!"
