here is the guide:
type in console
map l4d_vs...
whatever map you want to play in, it doesn't have to be a versus map, but recommended.
Then type.
sv_cheats 1;director_force_versus_start 1; director_no_human_zombies 0
Then die.
Should look like a regular versus game, and should be on infected now
director_force_versus_start in console again once next round has started.
Survivors should be heading out now by there selfs
Once they left, type z_spawn hunter, or z_spawn boomer, ect, which ever you want to play as.
You will spawn where you are pointing or standing, survivors may wreck you in the process half the time.
Survivors cant win.

TROUBLESHOOTING: Sometimes at the beginning of games the safe house door will get stuck and start making a locking noise over and over, and you wont be able to spawn. So if you dont really care about the survivors and just ♥♥♥♥♥♥♥ about alone you can type z_spawn hunter or smoker or tank w/e without having to wait on them. But if you need the door fixed try ent_remove in console while pointing at the door, I crashed once trying this but works fine for others I hear.

I just made the group private to kick some people that is trying to steal accounts. Remember: Never Ever tell your account username or password to anyone or anything.

If there is something the steam staff wants to say to you they will send an e-mail. They never contact you in steam chat. I hope you all know that.


Edit:

STEAM WILL NEVER ASK FOR YOUR PASSWORD!!!

Enter the Steam control panel then select the "My Games" tab. Right click "Left 4 Dead" and select the "Properties" option. Select the "Set Launch options..." option. Enter -console as a launch option. Start the game. A console window will appear at the main menu. Type bind "f12" "toggleconsole" then press f12 to open console. Remember, always turn sv_cheats to 1 before use any command. HOW? just write: sv_cheats 1 in console.¨
