Metroid Prime: Federation Force allows you and three other friends to co-op a number of different missions set in the Metroid universe. You hop into specialized mechs to kill foes and complete objectives. If you get bored of that, you can compete in a game of Blast Ball.
Features:
- Up to 4 players take on a variety of co-op missions in this first-person, sci-fi shooter set in the Metroid universe
- Work together as a team to clear out enemy-infested bases and complete objective-based mission
- Take on enemies with a blaster and special sub-weapons
- Aim using the Nintendo 3DS system’s gyroscope
- Join a pick-up game of Blast Ball, a 3-on-3 sci-fi sport in the Metroid universe where players shoot the ball into the opponent’s goal to score
I told you so. If you're still interested, you can pick this game up for the 3DS in 2016.
