Valve is looking at the possibility of implementing cross-play between Left 4 Dead and Left 4 Dead 2 and says that mods created for the first game should run fine in the sequel with just "very minor amounts of work."
The uproar over Valve's announcement of Left 4 Dead 2 at E3 is old news by now. A number of fans were, and are, convinced that despite its promises to the contrary, Valve intends to stop supporting the hit online zombie-shooter so it can concentrate on the sequel. But in an interview with TotalVideoGames, Valve Marketing Director Doug Lombardi said the developer isn't just going to continue supporting Left 4 Dead, it's actually looking at ways of making it cross-compatible with the sequel.
"That's something that we're trying to work out right now, the details of it," he said. "So nothing specific to say today, but we understand that it's a very valid thing to be working on and looking at."
He also explained that modders creating content for Left 4 Dead would find it easy to translate their work to Left 4 Dead 2. "With the mod stuff, if you're making stuff for Left 4 Dead it will work in Left 4 Dead 2 with very minor amounts of work to bring it over," he continued. "So we feel we've made good steps on that side and now we're looking at how we manage that for folks who buy the first game and sequel."
