I want to buy the game dead by daylight for the xBox. The special edition (older version) is available in the shop.
A friend also has Dead by Daylight on her Nintendo Switch, but the nightmare edition (newer version)
Now my question is whether I can play online with her despite a different edition? So in crossplay
The edition you buy includes the normal game and additional killers and survivors (it depends on the edition that comes with it).
Crossplay is available for all consoles, which means you can play together with your girlfriend as long as you both own the main game, which should be included in every edition.
