Once again, the event was held in two parts, Stage 1 and Stage 2, with some participants attending both.
The game was set during a fictional match where the Antlers Legends and Taito Obaken Legends were playing when a zombie pandemic occurred. The story involved the spectators (participants) solving mysteries to save Kashima Stadium from the zombies.
Antlers Legends included OBs Narahashi, Suzuki, Akita, and C.R.O. Nakata.
During the match, a cast member infected with the zombie virus fell onto the pitch from the stands. The game was disrupted, and the match was canceled. Then, fictional self-defense force members appeared and explained how to survive the zombie virus, marking the start of the game.
Zombies were everywhere: on the 2F concourse, 4F concourse, and in the parking lot.
In addition to Narahashi, Akita, and C.R.O. Nakata, Shika-o and Hustle Komon were also infected with the zombie virus. Since Shika-o and Hustle Komon did not attack even when infected, some people took commemorative photos with them.
Those who cleared the mission were able to open the doors leading to the players' locker room and press conference room on the 1st floor. Of course, zombies attacked there too.
When participants used the pistols, which were available for the first time this year, the zombies temporarily entered a state of suspended animation. Taking advantage of this, participants searched the rooms on the 1st floor to solve mysteries.
The first 100 people to solve the mysteries were able to participate in the final mission on the pitch. Success meant recovering the vaccine for the virus within the time limit. Both Stage 1 and Stage 2 successfully reached the final mission.
