Can you use sv cheats on Left 4 Dead 2

You can only use sv_cheats on a "Single-player Listen Server".You can do this by opening the console and typing in "map <Map Name> (ex c1m1_mall will start you at the Mall on "Dead Center" and c2m5_concert will start you from the Finale of Dark Carnival.)Type in sv_cheats 1 and now you can play though that campaign using the cheat codes

Note 1:You need the Developer Console Activated [See Quote Below] Quoted from the Valve Development Community Wiki:
The console starts disabled. To enable it, load the game and visit Options > Keyboard > Advanced. Once enabled, it can be opened and closed by pressing the button above the Tab.
(This should work regardless of your keyboard layout. If it doesn't, add -console to the game's launch options and type bind your_key "toggleconsole".)


Note 2:You can "Try" and get people to join using the "connect " command.
Note 3:Do NOT include the <>'s in the "map" and "connect" commands
