Left 4 Dead Zombie Genocidist/The Littlest Genocide Guide FASTEST completion

Some Mature language in this video, but it's an M rated game... so kids shouldn't be playing it anyways. Make sure not to overheat the machine gun. Let off it once in a while to cool down. just makes it go a bit faster if you do. Codes used: sv_cheats 1; noclip; sv_clips 0 bind (key) "sv_cheats 1; z_spawn zombie; z_spawn zombie; z_spawn zombie; z_spawn zombie; z_spawn zombie; z_spawn zombie; z_spawn zombie; z_spawn zombie; z_spawn zombie; z_spawn zombie; sv_cheats 0" There is a faster method, but you have to download a map for it. This is the fastest method without mods/ad-ons Check me out on Twitch Garh1993
