The initial build everyone currently knows about that I visited had only No mercy and its chapters, However I was able to find this build through YouTube comments, I believe its the second build out of potential numerous others, (hopefully earlier 2007 builds) however this seems to be the same time frame of the previous build. I'm still seeing what campaigns work and what maps dont work, most crash immediately or upon loading. This seems to be an early build of the Town combined with church portion of Death toll "l4d_vs_smalltown"

Haven’t played for awhile and I joined a random game and saw all this stuff no clue what it is

I know crashes are inevitable with this build but I can't even join a game or add bots without it crashing. Can someone help?
