At least, that's what the screenshots look like at first glance. But listed below are some of the things I have found about this game (taken from my facebook page mind you):
"Underhell Chapter 1:
3500 lines of dialogue
24 voice actors
Unique choices that impact your story... even carry across chapters.
6+hours so far... nobody knows how long it is yet!
Nonlinear levels with lots of sidequests
Unique "free aim" system that uses no crosshair and moves the gun around the screen as you walk... ironsights have never felt so great!
Massive improvements including inventory system, dismemberment, and the porting of the smod engine (which it uses) to the orange box engine.
Underhell: The House (world hub):
Exploration and scary, Amnesia the Dark Descent-esque stuff.
Dream cycle and waking cycle
Discover the secret behind the main character's wife's aparrent "suicide"
Overall I'd say that's quite an achievement, considering it's made mostly by ONE F**ING GUY OVER THE COURSE OF 3+YEARS... and some help from tom stoffel and his coder friend, Charly! It's also a COMPLETELY FREE HALF LIFE 2 MODIFICATION.
Oh yeah, one more thing. THE SOUNDTRACK IS AWESOME."
As you can probably tell, I'm a huge fan of this game. I've been waiting it's release for two years, and it finally just finished downloading. If any of these things appeal to you, I suggest checking out Underhell's moddb page here:
Thanks again, and like always Get Randominated!
