Mii Force (known in Japan, Britain, and Australia as StreetPass Squad) is a DLC game for StreetPass Mii Plaza. It was developed by Good-Feel. Upon purchase of the game, the player receives the Mii Force Helmet.


The player is hunting the villainous Gold Bone and his Gold Bone Gang, who are plundering various planets across the universe; the player recruits Miis and mercenaries to help defeat them.

There are three special goals per level:

  • Reaching required score - Collecting gems and treasure
  • Collecting all 5 treasures - Treasures may be in enemies, enemy groups, walls, and gem cases
  • Completing with all pods intact - Finishing the level without losing a pod (restarting a level gives you another chance at this)

Allies can be hired by:

  • StreetPass or SpotPass
  • Hiring a mercenary for 2 Play Coins (Dog or Cat)
  • Hire an old ally for 3 Play Coins (Limit of 3 per mission attempt)

Each character's ship matches their color.

If the player is hit, they lose one of their pods. If they lose all of their pods, they can try again up until they lose on their 3rd attempt.

Failure of the 3rd attempt will end the mission, and any treasure found will be kept and the player's current squad will be dismissed. Then a cut-scene will be triggered with Gold Bone bragging about his victory over the player.

A title is obtained upon completion of a mission, with a total of 120 titles being available. Each area has a high score which can be compared to other players who own a copy of Mii Force; their scores are updated when they are StreetPassed with.
