I had this one tucked in my library for a long time, and if you ask me i would say for far too long in light of my recent experience.
I was positively surprised by how well made and paced this game is.
Despite being enclosed in a giant building trying to uncover the secrets of some kind of an alien outbreak and understanding the story of our main protagonist, i didn't feel claustrophobic nor bored of the same design or limited verticality thanks to a nicely crafted map and open fighting areas crowned with amazing visuals.
But the story was what made this game shine ! The intrigue, the build up, the ending ... simply excellent
And last but not least, artistically this game was really well made ( Spoiler : the maze mission settings was flawless)
Highly recommended !

I somewhat enjoyed playing this game, but at almost every point I felt like there were better things to be doing. I didn't enjoy the combat, the exploration, the service weapon power-up system, or the reading. There is a lot of tedious reading and video watching/audio listening to get the story, but what's the central story, side fluff, and in-between is not very clear. The intended ambiguity in the story doesn't help. Every story piece and every activity in the gameplay loop seemed like it would get better just around the corner, but never quite got there. And a couple of the key puzzles were really just unclear, not helped by not having the tools you use in the rest of the game. There's almost nothing that I couldn't overlook if it were the only issue, but sorting through it all, there are no parts without issues, and there is nothing I can wholeheartedly recommend about the game.

This became one of my favorite games, I really liked the scientific weirdness. Great history, nice graphics and one of the best playability.
