Just finished playing it. And now I am writing this review while still in awe after playing this game. At the start everything seems confusing and i have no idea whats really going on. But slowly it became clearer as we go along the story. I like the parts when you have to solve puzzling machinary and computer system to access the maze of underwater facility, while at the same time have to avoid / running away from freakish robots. This game really push your brain to think. I can still feel the chills when going deep into the ocean abyss, like 3000+ m depths. Great game. Will definitely play it again in the future.
