Underhell is a Source Engine game developed by the Underhell Team in collaboration with We Create Stuff. Underhell Chapter 1 requires ONLY Source SDK Base 2007 installed. No Source game is required.
What can i say? This is amazing, plays kinda like fear. Very well scripted and put together. Interesting concepts used in all aspects of the game, and i think that this project has something that has been missing in mod development for awhile.
*Only downfall is that not everyone has movements, some npc's are just frozen. kinda takes away from the game.
