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 Steam Workshop: http://steamcommunity.com/sharedfiles/filedetails/?id=121068229
If you like my work please consider making a donation! All donators receive perks in Helm's Deep Reborn, read more about it here: http://steamcommunity.com/workshop/filedetails/discussion/121068229/312265782622749732/
I am also working on a campaign called "The Lord of the Rings campaign" featuring Moria and Mordor which will be released on Gamemaps once they update their website which they have been talking about for a long time.
