This game is absolutely stunning. The entire game is well planned out, visual, story, music, combat system is top notched.
I usually hate backtracking and revisiting place like any older Metroid games. But this one is actually wasn't bad.
Do expect to die quite a few times vs bosses in this game and trying to escape E.M.M.I. not an easy game but once you learn the trick, it gets easier and quite satisfying.
One of my favorite Metroid game
