I would have to say that Metroid Dread has become my personal greatest game I played in the last 10 or 15 years. It's setting, the movements, the boss fights, the ambience, everything is tied together so well that I don't know how they can top Dread with a sequel.
First the Gameplay and Controls, It's standard Metroid fare here, but what you have is a control scheme that not only uses about every button on the controller, but it does so in a non-complicated way, it's almost seemless! Traversing though planet ZDR felt so damn smooth it was like cutting through butter!
Planet ZDR also has some interesting baddies waiting for you that will have you killing through them, both old and new are here. The biggest addition is the E.M.M.I. They are truly terrifying, thankfully they are in their designated areas otherwise this game would be alot more stressful. They search for you and can see through walls or even hear you...they're super scary! And the boss fights here also make you feel like a genuine badass as you fight through them with a crazy aresenal.
I can't say much more without spoiling it, and it shouldn't spoil it if you haven't played it yet. If you are a fan or Metroidvanias this has to be on the top of your list and should be respected!
