Very impressive to be a half life mod, the history is intriguing and effects looks very well, same as music. There is only defect, it's too short and adicctive!!


Blown away! Wow. What a ride!
Deep deep story, amazing atmosphere.
Smooth and raw action :D

I've never seen a mod quite like this before. From the start, I was immediately immersed into the world of Underhell. It feels so refreshing to see a mod like this come about. I can't wait to see what happens in the next chapters. What a fantastic mod. Shouldn't be missed to whoever has HL2 installed :D.

This game was truly amazing in all ways I could name. At first when I spotted it,it seemed as though it would be another action fps, but to my surprise it was much more than that.

This game flawlessly combines a good mix of depth, creativity, and a intuitive storyline as you progress through a creepy house filled with mysteries,unlocks, and nightmares.

Though the games house gives plenty to download for,it also has a VERY interesting combat system that kept me playing it till the end, and wanting far more after it was done, and when I realized it was only a prologue, i was shocked.

10/10, you have earned all my respect for a great mod that feels like a whole separate game entirely.

I was surprised how well made this mod is. I highly reccommend it.

A beaultiful story and an amazing gameplay... Nothing to complain, and waiting for rest of the chapters.
This mod deserves a solid 10!

great mod. an epic win

amazing just amazing.

Even though this game currently only contains the prologue, it is quite obvious that the story is the top priority for this game. Never before have I played a game that contains just as much story as game-play, and just as much scares as much action.

The House is so far the only place that contains the scares, with several mysteries to uncover, and dreams to sleep through to uncover a mysterious story that probably means more than what is ahead of you in the next chapters.

The thrills and horror only go so deep for me, as I practically skipped the scary parts because I was to scared of my life to even continue forth with anything involving the House. So I just grabbed the keys, my gear, and moved my *** onto the Prologue story. Unfortunately once I made it past the Prologue I wanted to see more of the House. That didn't do too well, as I nearly soiled myself.

The action and game-play itself on another hand is absolutely superb in almost every way. Your firefights are gripping and really demand duck n' cover instead of run and gun. It sounds repetitive, but the developer of the game really managed to make the battles intense no matter what the situation at hand, reloading, shooting, taking cover, either way you're getting pounded with lead in a very tense and uncomfortable manner, which pumped my adrenaline A LOT.

This game is highly recommended to anyone who is looking for good shooting, scares, thrills, chills, twists and turns, and one hell of a good story. I give it a 10/10.


If you are reading this to think about downloading, then stop thinking about doing it and get the mod! This was an extreamly good mod.
