Underhell is an Episodic Story Line Single Player Modification for the Source Engine.
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, his 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 mod begins with a wake up call from Frank ordering Jake to come down to the station.
An armed group of highly trained soldiers have taken control of a hospital and all its personnel.
But Jake will soon realize that this is more than just a hostage situation.
The first idea of making Underhell came out in early 2005, the mod emerged from Dawn Of The Dead Counter Strike Source game type, which is about playing with a few players on a human side team, against over 40 bots in the other team, with knives only.
Since at the time Left 4 Dead did not exist and there was no zombie mods, this was the best way for players to experience coop zombie survival.
I played this gametype with SeriousK, an old friend, and we talked about making a coop mod with this idea set inside a huge underground prison facility where the objective would be to survive and escape. Each floor would have a checkpoint where dead players would come back to life.
Which is exactly what Left 4 Dead is now, but at the time, there was nothing like that.
We decided to make it happen. The team grew over time, and we reached over 20 members throughout development. Unfortunately, not much content was created and I ended up working alone on the project.
The Prologue was originally designed as a very short introduction to the gameplay mechanics and characters, I suppose I got carried away…
People who were following the mod kept thinking it was dead, I was silent for long periods of time, and didn’t update unless I thought I had something substancial to show.
Inspirations and Influences
As you can read from the credits, you can see a lot of games and movies in there, but one of the most obvious that people have been calling numerous times is F.E.A.R by Monolith studios. Now if you keep track and read around, you will see that Underhell was in development since 2005, if you see the “Underhell Trailer 3″ video, with “Her” chasing the player in the house, you will see that this video was uploaded in 2007, but at this period we announced the mod, it had been in development for over 2 years…
The original idea of having a female haunting the Main Character came from the japanese movie JU-ON, after F.E.A.R was released it gave us a new Souce of Inspiration.
The very first idea of the mod was to make a multiplayer zombie survival game like Left 4 Dead, but focused in an Underground Base. We wanted to add new enemy types, such as a huge boss similar to the Nemesis in Resident Evil 3. This boss would spawn and attack the player at random times and could only be driven away once he took enough damage. At the end of the game, he would return as a final boss who the players could finally kill.
We also considered some sort of omnipresent enemy called Her that would sometimes appear as a hallucination with accompanying creepy music. She would attack players located in dark areas. Whenever the music kicked in, players would have to stay within the highlighted areas to avoid being taken by Her. She would operate similar to the Witch in Left 4 Dead. When I saw the movie JU-ON and the character Kayako, I knew I found the perfect look for her.
