If you're working your way through the Crime Boss: Rockay City achievements, we've got some good news for you. 505 Games has made all Crime Boss: Rockay City DLC free on Xbox for an unspecified amount of time. Four Crime Boss: Rockay City DLC packs now free-to-keep on Xboxhttps://www.youtube.com/watch?v=CpoGODP_TVQ&pp=ygUjY3Jpb...
As far as we can tell, 505 Games hasn't said how long these DLC packs will remain free to claim, so you'll probably want to grab them as soon as possible from the Microsoft Store. The two meatier DLC expansions are Dragon's Gold Cup and Cagnali's Order, both of which have their own DLC achievements.
