Microsoft has bolstered its Xbox One backwards compatibility lineup today with two new games: Mafia II and Prey.

Both Xbox 360 games are now fully playable on Microsoft's bulky telly box, so if you have them on disc simply pop it into your Xbox One and start playing. On the other hand, if you have a digital copy stored in the vaults somewhere, it will appear in the 'Ready to Download' section of the My Games tab. 

The good news is you can still pick them up if you don't own them at all, as they're currently available on discount as part of the Xbox game deals for the week. In case you missed it, Splinter Cell: Conviction was last week's addition to the growing b/c lineup.

Developed by 2K Czech, Mafia II was originally released in 2010 for PS3, PC, and Xbox 360, and takes place in the fictional Empire Bay, which is based on New York City. The mobster sequel features an open-world setting and sees players rising through the criminal underworld as Vito Scaletta. 

Finally, Prey hit stores in 2006 for last-generation systems and is well known for its arduous development cycle, having originally started out production way back in 1995. Human Head's planned sequel was ultimately scrapped before being revamped by Arkane Studios into the reboot we have today.
