Go up the stairs at the side of the ship twice. See if this has helpful indicators as to where the bridge might be.
This deck is split in two. You spy plaques on nearby wall. "Quart." on right wall and "Emerg. Gene." on left pointing forward. Helpful.
turns on radio Give me a hammer!
Loot room 7 before going and grabbing the tools that are in room 2 (of floor 1)and smashing the self and wall of room 9.
Room 7 has only one bookshelf containing few thin binders. You pick two and tuck them under your arms and make your way to lower deck.
Seriously, you have only two hands and no backpack. How do you expect to carry all those tools in addition of binders and volley balls?
Loot 2 if anything's left.
Oh, there's plenty left. Arc welders, power tools, hammers, wrenches, various metal sheets. Pick your poison.
Get up, explore through unnamed door.
This seems to be dry food store. There's cabinets full of bread, spices and other dry food. Well, not exactly full. After quick examination you find out that only one quarter of food capacity is filled.
"Sir, I've got some red wire running from the middle to the bow, it's a thick as my arm.." Dive lower, let's see what's under if I can reach it, otherwise, go back, surface, go inside the ship and see if I can go into the lower compartments.
There's nothing under the cable other than few hundred meters of water. The cable itself is clamped onto hull on its whole length.
That done you get up and then down on to second deck from room C. This deck has much more vertical space than the the one above, but is completely filled with water. On south side there's large and high block, probably engine casing. On the northern wall down on floor level you spot a window and a door right of it. And of course more doors ahead.
Go ahead with hull examination. Make fuel a looting priority. Also oars.
Ok. Remind me about this around Sunday.
