If you've been waiting for the right time to bite on Left 4 Dead 2, your patience has paid off. Valve has just released a hefty new update, just as it puts the game on sale for 75% off. This also comes among a tease of several new L4D-related updates coming soon.
The Cold Stream update is a community created campaign in which you'll battle zombies while avoiding a watery grave. The update is free, and also includes the L4D1 campaigns Blood Harvest, Crash Course, Dead Air, and Death Toll. Meanwhile, you can also now play with all Mutations all the time. The Xbox 360 version will be updating soon as well, but will require the Passing DLC for access to the Mutations.
Other announcements include L4D2 as a Games on Demand title on Xbox 360, the impending release of the game on Linux, a Minecraft-inspired community campaign, survivor skins coming to the Xbox 360 version of Minecraft, and the addition of the characters to the Source Film Maker.
If you're tempted to get the game, be advised that it's $4.99 for roughly the next 24 hours on Steam. You would be wise not to wait.
