Nintendo has updated its StreetPass Mii Plaza with four new games, and new Mii bonus items to boot. Unlike the free default StreetPass games, though, these are available for purchase for $4.99 each, or $14.99 for the set of all four.
The four new games include Mii Force, a sci-fi shooter, Flower Town, a virtual garden, Warrior's Way, an army-building strategy game, and Monster's Manor, a treasure-hunting puzzle game. Each of these use the StreetPass functionality to gather new parts of the experience, like weapons, seeds, troops, or pieces of the mansion floor. The update that opens the new games for purchase also gives the StreetPass plaza a makeover, adds some more greetings, and brings four new puzzles for Puzzle Swap.
Playing the new games earns you tickets that you can redeem for new hats and outfits for your Mii characters, like a Luigi costume, Yoshi's Egg hat, Super Mushroom hat, and Star Hat.
