Valve hat in der Nacht ein Update für Left4Dead 2 veröffentlicht. Hauptsächlich wurden Änderungen am Balancing vorgenommen. Wie gewöhnlich wurden bereits alle Windows-Gameserver mit dem Update versorgt und alle Kunden mit Linux-Gameservern können es ab sofort per Knopfdruck auf "Spiel updaten" im Webinterface einspielen.

Changelog:

Addons
- Client‘s custom HUDs will be reloaded when changing between Official and Non-official servers.

GamePlay
- Bullets that first pass through an infected character before striking a Survivor are now ignored as friendly fire.
- Fix for survivors speaking The Passing Finale lines in other campaigns.

Versus
- Charger now receives 300 points for any Survivor that is insta-killed.
- Charger now receives 100 points for any Survivor that is insta-incapped by a charge.
- Any infected that causes a Survivor to stumble into a "ledge hang" situation will receive 50 points.

Tank
- Tanks go into a stasis when they spawn and leave stasis when the human player takes over.
- Tanks in stasis are invisible but still show a glow to the infected team.
- Tanks do not attack when they are in stasis.
- Tanks in stasis cannot be set on fire or damaged.

SDK Tools
- Fixed crash whenever a VMT was loaded in L4D2 tools mode.
