Hey 101STBelialMSGT
Honestly, I'm not sure, but I don't think the skin will be a permanent addition to the EA app, since it's tied to the Dead Space event in Battlefield 6, which, funny enough, ends today. So I wouldn't be surprised if the skin disappears soon as well.
That said, I think this also ties into some feedback I've seen about the EA app before. It'd be pretty cool to have a selection of different game-themed skins to choose from, especially if you could set one as your default. Definitely something I'd agree with, haha.
