3 Permanent weapons for the entire game :), helps with Boss Fights

Hey i recently discovered if you pick up three guns, when you double pack the last one put it in the machine, quickly jump out the portal and pick up the closest gun, jump back in the portal and as you pick up your gun hold square and press melee same time, is helpful for boss fights such as the Rat King ;), Nunchucks, Double Kendals and a LMG for the whole fight <3
