If you are a player of Left 4 Dead or Left 4 Dead 2 and are seeking a challenge with more encounters with zombies and aggressive special infected, you have come to the right place.

If you find playing on Expert to be too easy, playing the L4D Challenge on expert should offer a challenge. All campaigns are possible to beat on Expert but may require some team work to do so. - L4D Challenge Details - If the server is not in use, you can start a game from lobby by using the following in developer console: mm_dedicated_force_servers 108.61.238.70:27015
