Hello my name is Daniel, also known as SeriouS_Samurai. I've been developing a map for the Source Engine since 2008. Today the map is known as Helm's Deep Reborn and can be downloaded via gamemaps: http://www.gamemaps.com/details/2664
As you may have noticed Helm's Deep Reborn is no longer available on the Steam Workshop, I manually removed it because the community had trouble downloading the map from there. I have plans to release more updates which means I no longer have to worry about the file size of the project.
Helm's Deep Reborn got featured by Valve and was added to Official Valve Servers. At one point PC Gamer featured my work in PC Gamer Digital Episode 3 and numerous articles have been written about the map.
