Left 4 Dead
The Left 4 Dead community has created a wealth of movies. They range from a simple collection of Nick’s profanity, to animated shorts, to full feature films.

Previously we would have to hunt around on Youtube to find all the movies but now with the new Steam Game Hubs, we can find all the movies in one place. To help us have all the movies in one place – if you created a movie for the L4D world - add it to the L4D2 Game Hub (We don’t have a way to attach the movies to a franchise so we are using L4D2 which incorporates both games). To do that, click on the "Videos" link on your profile page and associate your Youtube account with your Steam Id and then select the L4D themed movies from your channel and attach them to the L4D2 channel.

With today’s update and Steam’s Beta update we should have all of the “error 55” issues resolved. If you are in the Steam Beta program, make sure to accept the update to the beta today as that was causing a conflict.

When we had the issue with "Remove plug-ins” many players added “-insecure” to their command line. After we resolved the issue, if you still had “-insecure” in your command line it would continue to give you the "Remove plug-ins” error. We have updated this error text to give you the correct information. If you get an error that you are trying to connect to a secure server in an insecure manner remove –insecure from your command line launch options.

You can view the complete release notes here.

The Steam Workshop website will allow you to browse, rate, and discuss thousands of community created add-ons and even install them directly to your game with just one click of the mouse. We are also going to try an experiment with the L4D2 Workshop that will allow content to appear in the L4D2 world even more seamlessly based on the community’s response.

Today, Team Fortress 2 is adding co-op and robots to their game! There is only one problem - don’t worry, robots are just the zombies of the future that’s not the problem – the problem is this is 6 player co-op not 4. So you’re gonna need to find a few new friends, a younger brother, your mom, someone, anyone to join you and your three friend to fight the lethal horde of robots.

Swords can slice up some fun. Chainsaws can tear apart the infected. But you need to get close for both and well… chainsaws are really loud! Time to go with the ultimate gun, you and three friends armed with M60s and unlimited ammo. This is going to get messy.
