Underhell is a Source Engine game developed by the Underhell Team in collaboration with We Create Stuff. Underhell Chapter 1 requires ONLY Source SDK Base 2007 installed. No Source game is required.

Chapter 1 took a while to make, but Chapter 1 was as long as a full game.
And it was full of content to do in it.

This is definately, the best game ever. It can't be considered a mod anymore, it's a game.
It has as much dedication as a game made by Valve.
Sure there's 2-3 problems but they're easily ignorable.
Get stuck in doors

A.I. is a bit off, I could never be stealthy because they had always found me.

Navigation is a but hard sometimes. I can never know where to go sometimes but I always figure it out.

This is definately something that should be made into a game. Valve should higher these guys and give them whatever they need to turn UnderHell into a full game.

I honestly believe that too.

I thank everyone in the Mxthe team for putting work into this, thank you guys.
