awesomness blood and gore trick
Ok, to actually do this, you need to look at 2 files, ..\Steam\steamapps\common\left 4 dead 2\left4dead2\steam.inf, and ..\Steam\steamapps\common\left 4 dead 2\steam_appid.txt. Open steam.inf with notepad or whatever, and change the line that says "appID=590" to "appID=510" and save the file. Go back one folder and open steam_appid.txt and change the number "590" to "510" and save. Now, you need to run the game from the .exe file located at ..\Steam\steamapps\common\left 4 dead 2 AND NOT run it through steam. If you run through steam, it will still be censored (note that you can add the left4dead2.exe to steam as a non steam game and that will work to run it uncensored). When you run from the exe, all steam features will still work, the overlays and all that, it will just think you're playing the Left 4 Dead Dedicated Server.
