Fortnite frequently does crossovers as you guys that play it know.
They did Marvel and John Wick a while back.
Right now, they are doing one with Borderlands 3, and you can get a claptrap animated back bling, and whatever the other guy on the box art is, as a skin.
It costs 2000 vbucks, but thats not hard to earn if you play the game, or if you like Borderlands enough, apparently you’ll get the fortnite pack for free if/when you buy the game between now and the end of this year.
