As promised, a major update to Valve's zombie shooter Left 4 Dead was pushed out for the PC version of the game today – Xbox 360 players will be served in the coming weeks. The patch, which will be automatically downloaded through Steam, addresses a load of bugs and exploits, adds a few tweaks and even introduces some new features.

Particularly, fans of the Smoker class will be pleased to note that they now inflict more damage and recharge faster in versus mode, making them much more powerful characters than before. Elsewhere there are nips and tucks for each of the remaining classes, including the Hunter, Tank and Witch infected types. Overall loading times have also been improved and a couple of client commands have been “cheat protected” in versus matches. The full patch notes can be found after the jump.
