Doug Lombardi of Valve has revealed they plan on making an announcement this summer on more Left 4 Dead DLC, proving they will "keep supporting Left 4 Dead 1."
The devs "haven't shown everything" coming in Left 4 Dead 2 yet, and in "8, 9 months" people will see "the method of our madness". Plans free weekends for L4D2 "post-launch."
"We plan to keep supporting Left 4 Dead 1. There will be some announcements coming before summer's out about what's coming there, and then we haven't shown everything that's in Left 4 Dead 2 yet," Lombardi told .
"I think 8, 9 months from now once everything's been out for a while and everyone's had time to see the complete product of Left 4 Dead 2 and see continued support for Left 4 Dead 1, they may sort of see what we were up to and what the method of our madness was there."
The announcement of a Left 4 Dead 2 hasn't gone down too well with portions of the fanbase, but Valve hope to prove that they aren't abandoning the original game.
"With Left 4 Dead in particular we've found that word of mouth really is the strongest thing," he told . "With Left 4 Dead 2 we plan do a demo before the game comes out that'll have multiplayer in it and hopefully we can continue the free weekends with the full game post-launch."
Left 4 Dead 2 is being released on Xbox 360 and PC later this year.
