Climb down the ladder! See if I can get anywhere that way.
You head down the ladder. On the way down you nearly kick another man in the head. There are two men here, aiming weapons at you. They do not look like the same people who you fought earlier, but seem very cautious of you. The dog is standing behind you.. how did it get down the ladder? You see a man walk out of an elevator at the end of the room, in a full black uniform.
"Nice ... gun. Well, we have three choices. We can go up the ladder, down the ladder, or into the elevator, which may go in one or both directions. The elevator in the medbay back there led to a smaller medbay below. Oh, and there was a third man with the two you just disabled. He went down the medbay elevator."
If the elevator doors are open, check for level buttons. Either way, lay on the floor and peek down below, listening for any activity, then climb the ladder enough to peek into the loor above and listen there as well.
You check the elevator's buttons. They go, from top to bottom:
Bridge
General Quarters 2
Telecommunications
General Quarters 1
Medical Center
Engineering
You Listen into the floor below you, you hear the faint sound of power tools in the distance. You move to listen above yourself, and nearly get kicked in the head, as a man climbs down the ladder. You and the man you met point your guns at him, extremely cautious. He points behind you, the other man is back.
Loot the syringes I shot earlier and wipe them relatively clean of blood. Follow the man who took the extra pistol.
You gather up the syringes, luckily none of them broke. You watch the other man as he checks the elevator, and then listens in on the floors both above and below. As he peeks into the floor above you see a man come down the ladder. You both jump back and aim your weapons at him, not sure who he is. He is wearing a federation uniform, but not like what the other men were. He points behind you, the other man is back.
Take all the tools if possible. If that's more than I can carry, take only the screwdriver and wirecutters. Then exit the storage room, sneaking quietly down the hallway. Observe my surroundings and any rooms I walk past. If I encounter anyone, reduce their sight to 30% for 5 seconds and hide.
You manage to grab all the tools. You walk out of the room and into the hallway. To your right, down the hall, you see the doorway leading to the engine room, and a few feet before it, is the door leading to the office. To your left, there is a bend in the hall, around it, there is the bathroom, and another room that you are unsure of, it has a ladder in it.
Arm myself with a pistol like the guards had and put it in my holster. Take as much ammo as I can. Grab a larger weapon (and ammo) to carry. Continue up to the next level via the ladder.
You grab a pistol, a rifle, and ammo for both. You hold the rifle by using a shoulder sling attached to it. You head up the ladder, and see a medium sized lobby area. There is a desk where a secretary would presumably sit, but it is empty. Straight ahead of you is a large armored door, it is closed. Above it is a plaque that says "Bridge".
