Vote for Underhell for the 2013 Mod Of The Year awards
Underhell is a Source Engine Game that will be distributed in Episodic releases.
Prologue has been released on March 3rd, 2011.
Chapter 1 has been released on September 1st, 2013.


Underhell DOES NOT REQUIRE HALF LIFE 2 to function, only Source SDK BASE 2007
(Go in your tools tab of your Steam library to install it, it's free !)


In Underhell you play as Jake Hawkfield, a Special Weapons and Tactics officer who recently married and moved in with his wife.

But soon after this happy event, Jake's wife dies under mysterious circumstances, leaving only clues that suggest she committed suicide. Jake falls apart. Only his boss, mentor, and best friend Frank is there to help him get over his grief.

The game begins with a wake up call from Frank telling Jake to come down to the station. An armed group of highly trained soldiers has taken control of a hospital and all its personnel.

But Jake will soon realize that this is more than just a hostage situation…


The Original Soundtrack for Underhell is being entirely composed by Tom Stoffel

Valve, what is wrong with you? This game is fantastic; how is it not on Steam already?
Come on, I need this! After the bull you pulled with Guise of the Wolf and ORION: Dino Beatdown/Dino Horde/Prelude, I need a reason to love you again!

CMON STEAM JUST PASS IT THROUGH GREEN-LIGHT ALREADY. Stunningly well made horror game, good voice acting, deep story with many mysteries that lie beneath, AND ITS ONLY CHAPTER ONE! Some bugs, but always can be fixed up no harm done, none of them are game breaking from my time on the game. I am on the edge of my seat waiting for the next chapter to see what it brings in, I have not seen such a great horror game in a while, this brings up that nostalgic feeling. It makes me happy to see this pointing towards reaching steam and getting through green-light. The day it does will be truly great, for both the developers, and us fans. I could go on about this game for possibly forever but I shouldn't So here you go, what i think about this game, I am no critic but I wanted to give my judgement on it, 8.4/10 Could use some polishing/bugfixing, but other than that its really good.
