A new update was released yesterday by Valve which fixes numerous bugs, exploits, and performance issues, as well as a few tweaks to gameplay. The game was made available in late 2008, and despite a very warm welcome, received criticism for the bugs and exploits in the game.
However, gamers will be pleased to hear that the new patch release notes mention many of the common complaints that players had, in particular the matchmaking bugs. The almost unavoidable co-operative element in the game means that most players who have played the game for several hours or more have probably experienced issues, in one form or another, in the matchmaking facility. Assuming that the patch fix-lists are correct, that should no longer be a problem.
Amongst improved loading times, improvements to the HUD and UI, and command cheats being disabled, the Tank and Witch now appear at the same percentage into the map for both teams: i.e. where the Tank or Witch appear for one team, it will appear for the next. The patch is already available for PC, through the Steam client, and will be made available for Xbox 360 users in the coming weeks. A full list of updates and fixes can be found here, on the Steam website.
