"You've accomplished a great deal in a very short amount of time."
I'd say that's about accurate. I just beat it in two marathon sessions over the course of 2 days.
This game was... Wow. It was incredible for all the right reasons. Every level I came across felt distinctly different from all the previous ones. At times it's a survival horror, at times it's a run-and-gun, at times it's a squad-shooter, and at times it's a puzzle game, all within the span of 13 chapters.
But, I'm getting ahead of myself. Review tomorrow or sometime soon after.
