It's a novelty on which Fortnite has kept a low profile — for a few days now, the Octuple VS Scratch skin has had some under-the-radar modifications.
Seemingly, it has been attacked by a virus, gradually turning red and black. The more you raise your levels while playing with it equipped, the more it evolves.
At Level 300, you will become completely infected.
To get it, you'll have to reach Level 60 of the Battle Pass, then you'll have to level up to see it change.
Even then, what should we think of this skin? Fortnite rarely does things randomly. There's a good chance Epic are showing us the beginnings of a virus that may infect Chapter 2, Season 2.
See you in February to find out!
