Yes, You can play versus on any campaign in both Left 4 Deads.
1st of all it's left 4!!!!! Dead and you have to play versus mode in the first. in l4d2, it is versus and scavenge.
bad
yea if a friend is there with you get them to sign in then play together
To play as a zombie, you must play on the infected team on Versus mode.
No I wish you could tho
In my experienced, you can't, I assume you to Play Versus and Crete Lobby instead instead Dedicated Server.
You can't become a zombie, but you can play on versus and become a special infected.
yes,on the main menu press x to play game with friends and on that menu press x again to create a lobby and pick versus
any player whos infected can dont matter if ur guest or not
No. You can play split-screen with a friend on versus. But if you are wanting to play online, you obviously need Xbox Live.
I believe playing as an Infected is only available in Versus Mode
You're playing real people over the internet when you play versus, so the difficulty depends on the skill of your opponents. Therfore, you cannot change the difficulty.
