The leaders of the Left 4 Dead 2 boycott have revealed that Valve has plans for more Left 4 Dead DLC after the release of the Crash Course downloadable episode.

L4D boycotter Walking_Target said that the new content could be "a new Special Infected, a new Campaign or new Weapon(s)," and added that "it's definitely one of the three, perhaps more".

Walking_Target also suggest that Valve has plans to address some of the issues that damage the current Left 4 Dead experience, including stacking and camping in corners.

Crash Course is planned for release later this month priced 560 MS Points on Xbox LIVE and free for PC. Left 4 Dead 2 is set for November 17.
