Hello! My name is Daniel and I've been developing a map for the Source Engine since 2008. The map is known as Helm's Deep Reborn and can be downloaded via the Steam Workshop: http://steamcommunity.com/sharedfiles/filedetails/?id=121068229
Helm's Deep Reborn is free to download & play but you need to have the game Left 4 Dead 2 installed in order to play it. My work 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.
If you like my work please consider making a donation, even if it's a small donation!
I am also working on a campaign called "The Lord of the Rings campaign", for more info: http://serioussamurai.webs.com/lotr-campaign
All donations are appreciated and I am very thankful for any support!
