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
