Escape?

   The space station airlock finally closed, and Sampson tore his helmet off.  He gulped in the air hungrily.  He'd been floating around out there for far too long, and the extra exertion from trying to escape those....things, had depleted his oxygen reserves.  He scrambled to get out of his space suit, the material sticking to his sweaty skin.  Halfway undressed, he tripped, fell to the station floor, and vomited.  What even were those things?
   A faint skittering sound came from the far wall behind him and he froze, eyes wide.
   Oh God, they were in here with him.
