for some reason, I can't see the marines. I noticed one game that I was bumping into invisible objects than I noticed the zombies were attacking nothing then i noticed blood coming from nowhere and then i noticed that there were no marines (best run-on sentence ever). I tried reinstalling, but that only worked for like one game.The barneys are fine tho. Help! On a completely unrelated note, I think the barneys should get a police reskin instead of being a black mesa security guards. For example, black shirt and black vest, change the badge, etc.
