Just in case you are confused:oh man, that game WAS trash along with the 3ds version. I can even describe it.
Im waiting on "Samus Returns" metroid ended with fusion and the prime series with 3. They really need to continue the story without metroid. Hell i saw the doom commercial the first time two days ago and thought it was a better metroid clone, obviously before i found out it was Doom
Wait which dev make that.
Metroid->Prime->Prime Hunters->Prime 2->Prime 3->Metroid 2->Super Metroid->Metroid Fusion. Doom was different from metroid prime in most regard.
I'm afraid the Nintendo's "Japanese-superior" policies break the heart of the entire Retro Studio, and further with federation force. They could at least add some real backtracking in there.
