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.
This game was truly amazing in all ways I could name. At first when I spotted it,it seemed as though it would be another action fps, but to my surprise it was much more than that.
This game flawlessly combines a good mix of depth, creativity, and a intuitive storyline as you progress through a creepy house filled with mysteries,unlocks, and nightmares.
Though the games house gives plenty to download for,it also has a VERY interesting combat system that kept me playing it till the end, and wanting far more after it was done, and when I realized it was only a prologue, i was shocked.
10/10, you have earned all my respect for a great mod that feels like a whole separate game entirely.
