Vote for Underhell for the 2013 Mod Of The Year awards
Underhell is a Source Engine Modification 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

Well that text with the title of the game or with number of chapter - those 3D letters - looks kinda odd, sometimes music loops are starting to be realy anoying, the fact that I need to press focus button to have a better zoom with sniper rifle also does not help and that realy slow cutscenes durning introduction of the rooms in the house. There is still more little things that I can complain in this mod, but...

Spank my @ss and call me Charlie - this mod is freaking awesome! The atmosfer is realy heavy, the gunplay is realy satisfactioning, AI of the enemy is realy cleaver, sound effects and dubbing is preaty neat (well sometimes dub sounds kinda poor, but in general it is realy good) and the story so weird but still interesting that I just want to play more to finally figure out what the hell is going on. If you fix some stuff and realese this on Steam you can bet your jagged moustache that I would buy the crap out of this game :D

I played through the first chaper, and I have to say I'm amazed. This is amazing quality, far better than most AAA games now-a-days. I hope you can get this out, because this is a great story already.

It's not. And even if it was, the game is about people coming back from the dead. So...
