Valve's evergreen multiplayer shooter (in its PC incarnation anyway), Team Fortress 2, has been patched with a new game mode called Highlander.
The mode is simplicity itself: it's a nine-on-nine team deathmatch in which each team must be composed of one of each of the game's nine classes and no more. So careful teamwork and playing to the strengths of each class will be absolutely essential to victory.
Also in the patch notes is Steam Cloud support for key bindings and custom spraypaint images, meaning you'll be able to enjoy your own particular TF2 setup at any machine without fiddling.
