Valve patches Left 4 Dead PC News

Valve has rolled out a hulking PC patch for Left 4 Dead that puts right a host of exploits and further tweaks the acclaimed co-op shooter.

The update is applied automatically through Steam. Valve plans to offer the same fix for Xbox 360 "in the coming weeks".

Of the changes (listed below), the "increased chance of getting the Tank or Witch" during Versus game modes scares us, especially as both will now spawn "directly on the escape route".

"Kill" and "explode" client commands have importantly been cheat protected during Versus matches, and crafty players can no longer spawn Infected bots or run away and teleport back to regain health.

Elsewhere there are nips and tucks for each of the Hunter, Smoker, Tank and Witch Infected types, plus overall loading times have been improved.

The full patch notes can be found below.
