Overall, this is definitely good and runnable.
I would number/letter the room descriptions instead of (only) relying on the key. As it is, I need to look at both the key and the description to figure out what a given room on the the map is. You probably have enough space to just label the rooms as well, to be honest, given the overall font-size used, and it would be what I would do if I was printing this out.
The font seems overly thin in places and difficult to read, but that might just be on screen. I think that it would be fine if it was printed out, but well, there is a ton of black, so that is not going to happen.
The cargo cut-out has a corpse, but the other corpses are only in the keys: consistency (or having the symbol in both) would be helpful, I think.
It is not quite clear what the HEAD is actually doing in terms of why it is killing everyone, especially if it can assimilate heads and similar. The note on the console is explanatory, but there is no indication of where this should be found or who wrote it - I assume that this is meant to be whomever is found in the Power Room.
Some nice environmental world-building in general though: it is pretty easy to follow the flow and how one might run this.
