On April 20th, the guys over at Valve posted this minor update
to the L4D blog stating that an update was coming with the final Cold Stream map. I'm a huge fan of the L4D franchise, but it seems that it is being left out of Valve's routine updates. No doubt they're working on a ton of stuff for only 300 employees, but I guess I made the assumption that Valve would be releasing more DLC like they do with TF2.
Cold Stream has been in beta for a year or more (I believe) and it isn't even their map, it is a community map that they're refining. The last official map/campaign was released in Oct 2010 if I'm not mistaken.
I hate complaining about this, but I guess I just expected a little more.
If Valve were to update L4D2, what would you like to see added, changed, etc.?
I'd like to see some new weapons. They've got a chainsaw, I'd like to see a flamethrower in the same sense. I think the chainsaw is a bit underpowered. The chainsaw's fuel just doesn't last very long. A better rocket launcher, maybe more like a bazooka. And a better AI, that can change map elements (especially weather elements), levels and components so each play through is totally different.
