Thread music to get you in that Half-Life 2 mood:
These aren’t all, just a small amount
"Train leaves in 5! Maximum one luggage item per person!" (All in-game)
"Sniper! (All in-game)
"Simple rebel camp"
"Nothing left" [Scenebuild]
"We never change" (Right around here I discovered chromatic aboration, and I now realize how bad it looks, please excuse me.)
Generic rebel posing
"Citizen musician pondering about what to play next"
"I walk this lonely road"
'Tis just a few of them, I might update this thread in the future with more.
Well, uh, yeah, please leave a comment stating something.
