Paradox Interactive has released Hunt for Aurora, new DLC for Empire of Sin, the gangland strategy game for PC, PlayStation 4, and Xbox One. The Windows and macOS edition is on Steam, and owners of the Premium Edition or the Expansion Pass are entitled to a copy at no additional cost. It introduces a new British gangster named Robin Kay, presumably no relation to the notorious Kray twins, who were not born during the game's setting. It also introduces Aurora, a diamond that lies at the center of the add-on's capers. Here's the plot:

In Empire of Sin: Hunt for Aurora, players will meet Robin Kray, the latest mob boss from across the pond, and his crime partner Sylvia Taylor, who bring their flair for the dramatic - and a taste for danger - to Chicago. Together, they’re chasing the famous Aurora diamond, and nothing will stand in their way. Ambitious mobsters can now try a new dual-wielding combat style and use Robin’s cunning leadership to leave a lasting mark on the city’s criminal underworld.
