If you want to download items for the workshop - fire up your game, choose add-ons from the main menu (We moved it), and browse the workshop or you can just make sure you are logged in here and start clicking subscribe. If you have any questions on the Workshop post them to this forum.

We will continue to feature new content on our blog at l4d.com and in fact will be overhauling the site to be more interactive and help us communicate about the new content and updates with you. We will add a new featured campaign next week.

If you are new to modding - visit here - https://developer.valvesoftware.com/wiki/Authoring_Tools/SDK_%28Left_4_Dead_2%29. The wiki is a good place to start. You can also post questions to this forum and we can add a new sub-forum if people find that useful.

If you are a current modder, make sure to update your authoring tools and you can use the Workshop Manager to upload to the Workshop.
