Sony has confirmed that its PlayStation 4 console once again outsold the competition in June.

The PS4 outperformed the Xbox One and other platforms, according to data from industry-tracking firm The NPD Group that Sony shared with GamesBeat. The company credits The Caped Crusader for giving it the win.

‚ÄúPlayStation 4 was the top-selling console in the United States in June due to the overwhelming popularity of the Batman: Arkham Knight PS4 bundles,” a Sony spokesperson told GamesBeat. “PlayStation 4 also led software sales in June.”

Batman: Arkham Knight was one of the biggest releases in June, and Sony had a co-marketing deal with publisher Warner Bros. Interactive Entertainment that led to Sony packing the game in with new PS4s. Sony even worked with Warner Bros. on a limited edition version of the console that put Batman artwork on the case.

All of this enabled Sony to outsell Xbox One for another month.

“PS4 continues to lead console sales in the U.S. and globally,” said the company spokesperson.
