He can't do anything as a spooky wraith cloud, unfortunately. Maybe that's fortunate for 76. The ventilation shaft makes for little elbow room, and the fact that he's carrying the bazooka and the syringes too (ditching the tarp, as the bazooka is strapped over and around his shoulder, and syringes tucked into one of his belts) only make it that much worse. It'd be nice if he could just ghost around forever, but it takes quite a bit of energy and focus.

"Keep moving." He snarls, his top half solidifying first, easing himself into the space so that he doesn't just wedge himself against the walls. He's got a little extra bulk on his shoulders, not including the weaponry.

The nearest exit will do. They don't have to move far. Just enough to get away from the room and into the next hallway. As they crawl along, they'll eventually come upon grates along the walls of their crawl space to see below them. Any place that's not a gaping hole or another trap room is ideal.
