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

I loved this game so much. Amazing work. This game was better than all other singleplayer games i have ever seen or played in my entire life. The game got me sucked into it, the plot, the emotions, the voice acting, the action.... everything! I wish I knew how to donate!!!

You, guys, are awesome! I like Underhell so much. The game has everything it needs : brilliant plot, scary horror part, exciting action part, great dialogs. Can't wait for other chapters!

This mod is a masterpiece! The story, realistic gameplay, voice-acting, unique atmosphere, scary situations, music, amazing puzzles during the dream sequences makes every moment extremely memorable. However, if you are planning to play the game, i highly suggest you to play it on normal or hard difficulty and since this mod hasn't been finished yet, you have plenty of questions which we might get an answer in further chapters. If this game will be officially released, i will buy it with absolutely no regret...

Nevermind about my previous guess the chapters were released a few years apart so I think the game will be released in a few years ;_;

@ViolentValentine Thanks for the help! I'm estimating about february 2015?

Before doing the digital paperwork about getting to Steam, the creators are making sure that the game will have it's own content instead of contributed one. Things like sounds, textures, models are being made from scratch. Also, the programmer is working on porting the game to Source 2013 which will grant performance improvements and support for Mac, Linux and VR devices such as Oculus Rift. If this job will be completed, getting the game to Steam is only the matter of time.
I'm basically retelling what has been said on Mod DB.
