Metroid Prime Federation Force is not exactly what everyone was begging Nintendo to make, it's less of an actual Metroid game and more of a Metroid-style mini game. I've been putting off talking about it since E3 because right after E3 I heard nothing but a negative reaction to this game's announcement. I can't entirely blame the Gaming community for being upset with this Metroid game because it's not what we were expecting at all, although that could still be the very thing that makes the game worth buying, who knows. This new Metroiduniverse game will be released in 2016,
"Join a four-player local or online squad in this co-operative sci-fi shooter set in the Metroiduniverse. Hop in a specialized battle Mech suit and work with your teammates to take down enemy forces and complete objective- based missions. Then, take a break and play a fun, pick-up game of Blast Ball with fellow troops."
I think I can understand the problem people are having accepting this as the next Metroid Prime game, they were expecting a thrilling tale with Samus as the star and an epic adventure, not a four player battle game with 3DS graphics, and a soccer mini game to go with it.
