Battleground Z (called StreetPass Zombies outside of North America) is one of fourteen sub-games in StreetPass Mii Plaza, developed by Good-Feel. It was added in the second major update on April 16, 2015 alongside Ultimate Angler and the StreetPass Mii Plaza Premium feature. In Battleground Z, the player's Mii must visit various locations in the city of Hobbiville to rid them of zombies, rescuing survivors and attaining their weapons in the process. Each level in this sub-game involves multiple missions that the player must complete in order to progress. By reaching certain milestones in Battleground Z, the player is able to earn Plaza Tickets.
Story
Battleground Z takes place in the once-vibrant city of Hobbiville, located within StreetPass County. When the player's Mii is riding the subway to shop for hobby supplies, they suddenly notice an abandoned smartphone ringing from the seat opposite them. Their curiosity leads them to answer the phone, next to which they find a mysterious vial. The person calling is Dr. Scarlet, who asks the Mii if they are "impressively well-armed" and urges them to find a weapon immediately amid the recent and overwhelming zombie invasion. Just as the player's Mii comes across a stray Wii Remote, a group of Shamblers — the most rudimentary type of zombie — somehow find their way into the subway car and begin their attack. When the zombies are defeated, Dr. Scarlet tells the player's Mii that she will attempt to create a cure for the zombie infection, though she requires help to succeed. She also reveals that the smartphone is her own, and that she lost it on the way to her father's research center. Before momentarily hanging up, Dr. Scarlet informs the player's Mii that there are survivors with unique and useful weapons based on their respective hobbies.
After safely making it to the subway station, the player's Mii will begin their quest to rid Hobbiville of zombies. Here, they will meet several identical Hobbiville residents who will provide weapons to fend off the enemies within this level. Upon defeating all the zombies at the subway station, the player's Mii will proceed to other regions of the Downtown area, collecting various weapons along the way. To allow the Miis at the local hospital to be flown to the Stadium where it is safer, the player's Mii must rid a nearby parking lot of zombies. They must then clear the zombies from a back alley to ensure safe passage. However, the helicopter is unable to land in the Stadium until the player's Mii defeats a menacing Mega Slimebacker and collects one of four cell samples required for Dr. Scarlet's cure.
On Dr. Scarlet's orders, the player's Mii will then enter the Shopping Mall area to clear out survivors in the quest to gain a second cell sample. Once all the zombies are dealt with, Dr. Scarlet learns that there is a fire in one of the mall walkways that the player's Mii is tasked with extinguishing.
