Uniform Sabaigaaru (Uniform Survigirl) - Official Trailer

Seven school friends go for a day out to a theme park ominously titled "Survival Land." There, they get stuck into playing war games, and fighting against park employees for fun. All seems well until they realize the weapons they've been given are actually real and the park staff that they think are playing dead, are indeed DEAD and soon after Undead. Trapped in the park alone the battle becomes all too real as they fight to survive against the ever increasing number of Zombies.
