Metroid Prime: Federation Force (Nintendo 3DS)

Metroid Prime: Federation Force for the Nintendo 3DS family of systems is the latest addition to the Metroid Prime series. Work together in a party of up to four players to complete missions laid out for you.
Each player takes on the role of a Galactic Federation soldier and pilots a blaster-equipped robot called a Mech, which they can use to complete missions. At the start of missions, you will be assigned several secondary weapons, and one of the keys to success will be deciding which weapon to assign to each member of the group. Between missions, you can enjoy a round or two of Blast Ball, a three-on-three sci-fi sport.

Also includes Metroid Prime: Blast Ball

Blast Ball is an original futuristic sport vaguely similar to soccer. Each player controls a Mech with the goal of hitting a giant ball and sending it into the opponent's goal to score a goal. The matches are multiplayer, three players against three, and the team that manages to gain a three-point advantage over the opponents or the team that is ahead at the end of five minutes wins. During the match, three different types of objects appear at random, which, if used at the right time, are the key to victory. Intuitive controls and simple rules make this game easy to learn and play.
