Killer..... That's what he'd been called since that day... Having just got out of prison (ok more like juvenile detention), 16 year old Killer is faced with the task of finding his sister in a world where gangs and gang fighting have become a legal sport that every school district participates in. He finds out that the only way to find his lost sister is by joining or creating a local gang and participating in the biggest gang tournament of the year, Brawlhalla. Luckily prison and an abusive father have his fight training covered.
