Updates (Left 4 Dead)

The following is a history of updates applied to Left 4 Dead. The updates, when on the PC version of Left 4 Dead, 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 itself. Note that most of the more recent ones have only been applied to the PC Version, and the Xbox 360 version has yet to receive the updates.
