Personally I didn't like the third part in the series. I was not a big fan of the whole action focused storyline, however I won't downgrade it because of that. I understand that Supermassive has to change it up from game to game.
What i will however say is that this was the glitchiest gamee out of the three. The game crashed and lost connection multiple times.
Textures are popping in and out on characters and even characters themselves sometimes glitch all over the place or are duplicated on screen.
The story was slow at the start but got into a very good groove during the mid section all the way to the end. The ending itself came super quick and I was surprised about certain characters fate. The ending seemed aprubt. Reminded me of Men of Medan.
I think it's worth playing if you like the series and you want to play all of them. But if you like horror/mystery focused games more, then skip this one and go back and play Little Hope.
