The air is getting worse. He has to find some way to get the systems back online. As much as he hates the idea he finds a fairly clean set of clothes and puts them on, certainly more comfortable than wandering around in just his under clothes.
He makes his way down the hallway to the stairs, with the electricity being so undependable he is pretty sure the lifts aren't working. The low oxygen levels aren't making the stairs a fun task, hopefully he doesn't run into anyone who can breath better in conditions like this. A map of this bloody place would be nice. There has to be some sort of...control room. Somewhere. Or a computer to override the environmental controls.
