Popular streamer LazarBeam has broke Fortnite's kill record for each game mode, or at least in a casual manner. Unlike competitive kill records, which pit players against each other, this one was based on private custom matches, and everyone worked together to allow LazaBeam to kill them all.
It was more of a test of how many players could LazarBeam kill before the circle grew too small. So while it's an interesting test, it's not very impressive.
LazarBeam Fortnite Kill Record: Streamer Sets 'Custom' Kill Records
LazarBeam starts off in custom squads match and has everyone join him. They all run up a ramp and fall to their death, while one person on their team is in charge of the reboots. At the end of the squad game, LazarBeam grabbed 160 kills. He went into Battle Lab and earned 2,721 bot kills. Finnaly, after creating a pit of death in Creative Mode, LazarBeam garnered 33,766 kills, breaking his old record on Creative Mode.
Why did he do this? Because no one else would. And maybe it should have stayed that way.
