Pretty good, although way too hard and easy in several areas. It's got a pretty good story and it's got some pretty cool concepts within the areas, so I feel like 8/10 is a good score for the game.
I like this game, but my big problems with it are difficulty and the second half. When it comes to difficulty, the absence of vehicle-jacking and dual-wielding ment it was harder for me to get past most encounters. While I generally don't like regenerative health, I wish there was at peast some pretty slow regenerative health, because it's abscence lead to so many deaths. When it comes to the second half... The Library. I hate that level more than the **** an exaggeration but you get what I mean). All in all, it's a great game, but it is held down by an insane learning curve and recycled rooms. Also why do they choose that circular room to recycle out of all the rooms they could've? It's established that those rooms are meant to be generators for Installation 04, so going by that, Two Betryals should be at least a couple of hours long.
