Welcome to my containment zone! Feel free to make any edits you deem necessary.
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 begins their quest to rid Hobbiville of zombies. Here, they meet several identical Hobbiville residents who provide weapons to fend off the enemies within this level. Upon defeating all the zombies at the subway station, the player's Mii proceeds 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 then enters 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. After the fire is put out, she also informs the player that survivors are using the mall as a base for supplies. Protecting survivors' supplies from the hordes of zombies requires defending a food cart at the mall plaza and retrieving bottles of water from the warehouse. The player's Mii must then vanquish and collect a sample from Belinda Munch, a large and insatiably hungry zombie located within the food court. When these tasks are complete, the survivors at the Shopping Mall are airlifted to the Stadium.
In the Uptown area, the player's Mii is tasked with rescuing more survivors, allowing them to access a bus system put in place by Dr. Scarlet. The tasks in this region include retrieving a lost dog, collecting fuel for the bus from the gas station, and clearing debris from the highway. The player's Mii is subsequently asked to scout around the cornfield that the highway passes through. Here, they are distracted by a row of Combustocorn in the middle of the road, allowing Bubba and Cleetus Rotts to ambush them. Fleeing in fright, the player's Mii then ends up in the middle of a field, where they must battle the two zombified farmers and collect the next cell sample.
Now in the Countryside area, the player's Mii must make their way to the power plant to collect the final cell sample and stabilize Hobbiville's power supply; however, doing so necessitates that they pass through a dangerous tunnel and subsequently defend the gates of a graveyard from zombies trying to escape. At the power plant, the player's Mii must repair four panels while fending off zombies and toggling light switches to make the glowing panels more visible. After fixing the generators, the player's Mii is required to pass through a hydroelectric dam, guarding an employee and steadily proceeding to the exit. Dr. Psymad is soon encountered at the power plant, where he is found dumping an unknown substance into the reservoir to create Voltoad. Once this boss is defeated, the final cell sample is collected, though Dr. Psymad is nowhere to be found.
The player's Mii finally arrives at the Research Center area, where a survivor is found in peril as they attempt to enter the facility. Once the player's Mii has entered the research center, they must defend the lab, preventing zombies from entering and sabotaging Dr. Scarlet's plans. Upon defeating all the zombies, the player's Mii encounters Dr. Scarlet, who is close to finishing work on her cure. In the laboratory, the player's Mii is asked to position four tanks containing components of the cure into their proper places on glowing floor panels. The player's Mii then accompanies Dr. Scarlet on the service elevator to the roof of the facility, though the both of them must contend with zombies that seek to steal the cure. At the rooftop, they encounter Dr. Psymad, and it is revealed that he is supposedly Dr. Scarlet's father in zombified form. When the player's Mii strikes Dr. Psymad, he resorts to releasing the zombification virus through a nearby spray machine, from which Dr. Scarlet planned to dispense the cure. After releasing the virus, Dr. Psymad consumes a potion that turns him into the much more powerful Super Psymad.
Once Super Psymad is defeated, he melts into a puddle with a small alien at the center who, as it turns out, was posing as Dr. Scarlet's father all along. At long last, the player's Mii is able to dispense the cure, restoring peace and harmony to Hobbiville and allowing its residents to enjoy their hobbies once more.
