Sucks to be Bill.
So is there any plans to create a Left 4 Dead 3? The last actual game came out in 2009 (Left 4 Dead 2) and the most recent DLC was 2010. I’m just curious.
Isn’t Valve allergic to the number 3?
There have been relatively minor official additions to Left 4 Dead 2 as recent as October 2013, I believe, (as well as bug fixes up to just a few weeks ago) primarily focusing on mod support. Now don’t get me wrong, the game has a great modding community and a slew of high quality mods available and easy to install through the Steam Workshop, but even such, organizing a group of friends or finding random people who want to play custom campaigns is a pain. And of course playing with the AI bots just doesn’t feel the same as playing through with a group of friends. I can usually trust the AI a little too much to be a little too consistent, and too expendable.
To more specifically answer your query about a possible sequel, nothing has been officially announced, and the only stuff I’ve heard about potential sequels is probably pretty much generic hopes and dreams of fans. On the other hand, apparently something called Source 2.0 is becoming a thing? I don’t know the details, but it seems likely that Valve will want to create something that runs in it. Or update their older games to run in it, like they did for Half-Life and the original Source engine.
There have been leaks for supposed “Source 2″ screenshots of the plantation house from the finale of L4D2′s Swamp Fever campaign. Mostly rumor mill but most people are pointing to a L4D3.
L4D2 was recently made free-to-play for one day, remember? A lot of people got the game then. This means that Valve is probably testing the waters to see if what happened to TF2 can happen to L4D2?
I dunno, I’m just babbling.
