After a month of PlayStation 4 exclusivity The Stage has made it to the Xbox One and PC versions of NBA 2K15. The mode went live for the two on Saturday.
The Stage is an offshoot from MyPark which involves 3v3 and 5v5 games with VC on the line. Wagers are capped but a higher maximum remains exclusive to PS4. Anyone can team up for games in The Stage unlike The Park and Jordan Rec Center where affiliations (the three factions) often prevent people from joining sides freely.
To reach The Stage enter MyCareer mode and from the main nav bar go to MyPark and then select The Stage (Ante-Up).
