Recently picked up Trepan2 on the summer sale, and I gotta say, this scratches all of the same itches that F.E.A.R. does for me. Its so god damn fun. If you haven't played it yourself yet, I really do recommend it.
It's even got me thinking about buying all of the guns I can legally source in it. I had only picked up my first USP 45 a month before starting the game. Now I'm looking at getting an SBR'd Vector in 45, an HK SL8, and a Springfield Hellion just to larp with.
