Fortnite’s in-game rocket has been launched, and it tore what looks to be a hole in the sky and right through reality itself ... and that tear is getting bigger and bigger. You’d think that this latest content update would address that situation in even some small way, but at least we have a new machine gun?

“The Drum Gun is a hybrid weapon that combines the stopping power of a rifle with the suppressive ability and fire rate of an SMG,” the Fortnite team explains in the patch notes. It holds 50 rounds, uses medium ammo and delivers 26/27 base damage. You can find it among the floor loot, in chests or in vending machines.
