I would say FUBAR (being a military term), But I've already taken that. And yes, I swear I'm still working on that mod, so don't go stealing its name!
I can't think of any good ones at the moment, But It's kind of hard to think up names when you don't know anything that heppens in the mod. Does this soldier escape? Is he picked up by G-Man? Did he get blown to bits by the nuke? How did this soldier get to be in Black Mesa? Did his Osprey crash? Was he brought in without problems? Little things like this can be of much help when naming something, so I would suggest giving some part of the story to us.
