Welcome to the Left 4 Dead Underground
For Help or support with installing the game or patches try the chat box located on the Q&A page. If one of us are online we will help you get your game working.
Note: As of 4-18-10, this website will have to be re-done. All focus is on L4D 2. Please see L4D 2 guide at www.tinyurl.com/l4dguide2 - Versatile
Due to recent experiences at Wordpress.com, any special L4D article dealing with patches and tutorials will be at this site. This site is still rough around the edges, but over time it will get better. The goal of this website is to have all the L4D information in one spot with the patches and the tutorials. It will become a lean beast to get you the information that you need in the least time possible - Underground Style. ~ Versatile [5-27-09]
