Ryota Sakamoto is transported from playing the hit BTOOOM! video game to being stranded on an island with a bag of bombs and no memory. It doesn’t take long to see what’s going on after the first person he meets tries to kill him. Someone is recreating the game. Ryota’s an ace BTOOOM! player, but in this version, there’s only one way to win: kill seven other people before they kill you! The action is ultra-violent, ultra-graphic and ultra-lethal as the ultimate blood sport is unleashed!
