WWE crosses over with the Rainbow Six with The Undertaker and Becky Lynch operator cosmetics bundles in the UbiSoft store. The bundle includes the skin, headgear, charm, card bg, and weapon skin. Each Individual Operator bundle can be purchased for 2160 R6 credits or 4080 R6 credits for both (for Thorn and/or Thorn operator).

I'm absolutely dumbfounded of this crossover. But I mean why not? It's not like a Rainbow Six operator (an elite multinational counter-terrorism unit) couldn't dress up as The Undertaker. I guess anything goes as long as it's like Fortnite.
