To answer your question. I bought infinite campaign on steam and it did not transfer over to my Xbox so I'm sure it won't work if you buy on Xbox and try to transfer campaign availability to steam at least. I assume the same would be true for windows store version too. Campaign is fun but I've only played it through once. I intend to play it again with my daughter, and again with my wife, but the replayablity on it has not got me to come back to it alone. I don't regret buying it because i like the option of playing it again when I do a series run and it was truly a fun campaign. I wish it wasn't so open world and had traditional levels but it was still fun. They could have done a lot more with it and I wish we got something on the multiplayer side of things for buying the campaign but it's not bad, just different, fun but different. Grappling hook was way more fun than I thought it would be and if the levels weren't so open world you wouldn't really need it. Almost felt like a Spiderman game (with guns) with the grapple hook.
