Okay sooo imma explain rq how i done ts

(oh yea ts isn't really level specific you can do it on any level that has a dual wielding powerup and terminal closeby)

Soooo you first have to give yourself a dual wielding powerup and then remove all of your weapons from your loadout and you will have the weapon that you had last time on the left/right side of the screen

After you done that js enable the weapon you wanna have and you have 2 different weapons on your screen

(oh yea don't refresh your weapons cuz it'll reset it)
