It appears Arkane’s Deathloop is set to release on Xbox consoles rather soon if a pre-order ad popping up on Xbox is any indication.
Spotted by reddit user Immediate_Exercise27, the store UI clearly shows a Deathloop pre-order card.
The only thing is, when you click the option, it takes you to a blank store page. Still, this means you can probably expect the game to be available sooner rather than later, as the PlayStation exclusivity period is almost up.
