3) When You Join Just Wait A Few Seconds Then Disconnect
4) Then On The Menu Go On Extras Then Developer Commentary Click Ok On All Dialogs That Popup
5) When Your On Map Select Choose Any Map (Again Preferably No Mercy I Tryed It Mostly On Finale) Then Click Ok
6) When Your On Wait A Few Seconds Then Turn sv_cheats On In Console And Then Type Kill You Will Die Then A Versus Mode Screen Thingy Will Popup (You Have To Wait A Bit Of A While For The Versus Mode Thingy To Popup Plus You Actually Do Need sv_cheats On To Kill Yourself)
7) When You Respawn You Will Be Infected Go On Console Then Type sb_all_bot_team 1 Then Your Bots Will Start To Go Through The Level On It’s Own. This Is Normal
