Battle Royale games are played online against 100's of other players. They blend different genres of games: survival, exploration, adventure, shooting and scavenging while introducing the last-man-standing gameplay.

"The name for the genre is taken from the 2000 Japanese film Battle Royale, itself based on the novel of the same name, which presents a similar theme of a last-man-standing competition in a shrinking play zone." - Wikipedia
