Okay, I know my PC is out of date but I have had this game run before. And, frankly is definitely not a graphics-heavy game.
What is happening, is upon map launch it turns the screen black and my Graphics Accelerator crashes. I've encountered this several times with games like Portal 2, CS:GO, Left 4 Dead 2, and of course Alien Swarm and obviously its newer release, Reactive Drop.
Needless to say, YES I am on unfortunate enough to be stuck with an intel integrated graphics card.
My only lead toward fixing this is a wild-goose chase of some program by a guy named "Sniper" with his Royal BNA Driver with "Source Engine Fix" as its this later version of Source ("Source 2011" supposedly) All links to it are outdated; thew dropbox file is "either deleted or marked as private"
Which has frustrated me to no end, as I have run across more than 3 threads saying this Royal BNA Driver has fixed all their Intel Graphics problems---- but the file is no longer available. I have found a version on some auto-archive website and it turns out to be the 32 bit one, I need the 64 bit one. Even more frustrating is the actual program has an update feature which sends me to either a dead website, or that same 404'd dropbox file.
One of the things I remember about fixing the Portal 2, etc problems is it involved either a 3rd party .dll file, or required a certain -launch parameter.
