Expanding the Mayhem

Left 4 Dead was originally made for X-Box 360 and then moved to PC because of its popularity.  There were rumors going around on the internet that Left 4 Dead will be released for the Playstation 3 as well, but that turned out to be only a rumor.  As of last year, the Valve team has been fixing things up and adding new features to further enhance the PC and online gameplay, such as versus and survivor mode.  Valve's main plan is to release more updates and such for the PC game version and then later on group up these updates for the X-Box 360 version.  The game statistics allow the company to personally see what is going well and what isn't.  An example of this is that they "flipped the order in which teams play the next round based on who was winning the round before it."  This gave players a better chance to play through the final map.  The game's playing percentage jumped 5% after that change, which is small but it's going the way they want it to.  Other than statistics, Valve gets direct feedback from players as well to help out what they should keep and change.
