Let's face it. Turbo Pistol, Multitasker, Future Sniper Rifle and whole list of other were all copied from other game.
Regardless Cubic got the permission to copy those weapons or not, we need to come up with ideas to remodel those weapons. Plus, this may tune down the backlash of "Pixel Gun is copying from Fortnite!" or "Cubic, Blizzard Entertainment will sue you!"
For remodeling ideas, make a sketch first how will the remodel may it look like and I will build it via Lego Digital Designer. A remodel design that has the most vote, I will build it.
