My favourite metroid game so far. Cool atmosphere, environments, exploration and I even found myself reading and enjoying the bits of lore you find. Of course its not flawless, while some previous irks of mine from SM and ZM are gone some new issues popped up to take their place.
This game could REALLY use a fast travel system, more so than the 2d metroids, despite being standard for the genre the amount of backtracking in MP is seriously asinine for no good reason.
Other than that I found the combat to be underexplored. The start of the game would lead you to believe that enemy design would lean towards weak points and weaknesses for certain weapons, and while that is present through the entire game to an extent, as you get further the game starts insisting more and more on these obnoxious color coded enemy encounters. These enemies are annoyingly bullet spongy and require a specific weapon to do any kind of damage to them. This isnt a weakness, its just straight up a limitation for the player. I have to admit these encounters definitely soured my experience of the game.
I really hope they learned from these mistakes in the subsequent games.
