Updates (Left 4 Dead 2)

The following is a history of updates applied to Left 4 Dead 2. The updates, when on the PC version of Left 4 Dead 2, will be applied automatically when you restart Steam, and on the Xbox 360, you will be prompted to update the game when you start it up. However, this only happens if you have Xbox LIVE. The list goes from the most recent at the top, and the earliest at the bottom. These are only the specific changes made to Left 4 Dead 2 itself. Note that the PC version gets the updates first, and that the Xbox 360 version gets all of the updates to that point in time in a pack. Due to this, it's possible that some of the more recent updates have not yet be released for the console version.
