Ryota Sakamoto is transported from playing the hit BTOOOM! video game to being stranded on an island with a day’s provisions, a bag of bombs, a crystal embedded in his hand and a hole in his memory. It doesn’t take long to see what’s going on after the first person Ryota meets tries to kill him. SOMEONE is recreating the game, and the island is filled with unwilling players, each armed with one of many explosive weapons called BIM. Ryota’s an ace BTOOOM! player, but this version of the game has no reset switch, and 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 in BTOOOM!
