The DLC, which has yet to be named or dated, will be a “map pack” and will not include any new story elements – only new campaigns. To start off with, the remaining three Left 4 Dead campaigns will be included in this DLC. Since it is being developed on what Valve likes to call “Valve Time”, the DLC will be released only when it is ready – but it will be sometime AFTER Portal 2 is released.
The Beta version will be available on XBOX, PC, and Mac – and you can make suggestions on what to include in a forum dedicated to the development of the “Cold Stream” DLC.
The main limitations is NO new audio or story. So what would you change?
Keep a watch here and on your Left 4 Dead 2 game (in the blog) to see what is in store for the future of epic zombie slaughtering!!
