You can only be the infected by playing XBOX LIVE or online. I am not sure about system link or LAN Network.
in the first left 4 dead the infected where the spitter, smoker, hunter, tank, witch, hord
there is no fast zombie in left 4 dead...there is however a fast special infected. The hunter is without a dout the fastest special infected in left 4 dead.

No
TANK
No, you can only play as infected in multiplayer.
not sure but the characters from left 4 dead 1 and left 4 dead 2 meet together and you get to choose between 8 characters.
You can't, the survivors you play as are immune to the disease the infected carry. So it is impossible.
no
The Special Infected were the Boomer, Smoker, Hunter, Tank, and the Witch. The Common Infected are everyone but the Four Survivors.
Yes it does you can as 1 of the 4 survivors or switch between special infected on the infected team
Yes, Left 4 Dead "Smoker" special Infected do shoot their long tongues at players.
