Valve has added the Steam Workshop created Helm’s Deep Reborn map to the official Left 4 Dead 2 servers, alongside an update which fixes an issue with dedicated servers and workshop content. The map, as you’ve already figured out, adds Helm’s Deep from Lord of the Rings to the zombie shooter. It sounds kookie enough to make me want to try it despite being horrible at L4D2. Have a look at the map for yourself through here. Thanks, D’toid.
