Ohohoh, j'ai la réponse a nos question ... http://www.shacknews.com/featuredarticle.x?id=1028
--> "Doug Lombardi: Yeah, so what we did was we took two of the Survivor campaigns, No Mercy which is the hospital mission and Blood Harvest which is the cornfield mission. And we said, okay, there's five maps in each mission, and what we'll do is, you play as Survivor until the first safe house, or checkpoint if you will. Then you switch sides and you rewind to the beginning and let the other team play Survivor to try and get that far. And there's points that are given to each team when they play as the Survivors only.
So it's almost like an offense-defense thing. You get the ball when you're on the Survivor side, and when you're on the Infected side you're just trying to keep the points down. And then you swap positions, and you get this Us vs. Them, when the scoreboard all of a sudden comes into play, and you have this cool competitive element that you can sort of wrap your head around.
It's not just, "I want to play boss Infected because I'm a griefer and that's my only purpose in life." We wanted to wrap something more around it and say, "If you complete this you won something." The teams have to switch each side so there's more of a, I'll use the really obvious word, it's more of a game now, rather than a "multiplayer mode.""
En gros, le mode versus, ce sera sur les chemin de la campagne, a tour de role, faudra avancer le plus loin possible quand on jouera survivor, jusqu'à atteindre le checkpoint et gagner le round, ou alors se faire latter par les infecté, et changé d'équipe pour a son tour jouer infecté.. etc... Donc, j'avais qu'a moitié tort, et vous aussi =°
