Yeah, if you buy it on Steam, you probably can get achievements in both versions provided you are logged into your Xbox account.Thank you !
Yeah, I meant the "Also on" link, sorry for being unclear. We don't actually get the game on Steam as well. But maybe those who buy it on Steam will have both Steam and Xbox achievements? (since they can connect to their Xbox account, a bit like the GTA V unlocks both Steam and ROckstar Social Club achievements)
