Inflatality currently features four battle stages and weapons, as well as 30 different customization options. Hojo says additional weapons, stages, and modes will be released in future updates.

At the moment, Inflatality is only available on Steam Greenlight. If the title is approved, it will launch on the store in October.

PlayStation executive Shawn Layden told The Verge that he expects PSVR sales to climb higher, remarking, "It's still just a million units." He added that sales should pick up this year as a result of Sony being able to better meet demand.

"We'll have freer supply in the marketplace," he added about availability in 2017. "We got to a point around Christmas where you would be hard-pressed to find VR anywhere. So we dialed back some of our promotional activity at that time because we didn't want to be promoting a platform for people to find out they couldn't get it."

Back in February, a report claimed that Sony was projecting PSVR sales to reach 1 million units by mid-April, so it seems like that was a success.

The PS4 plays PS3 games through the streaming service PlayStation Now and PS2 games through the PlayStation Store. However, people need to buy the games again, even if they owned them on the earlier hardware.

By contrast, the Xbox One offers a catalog of more than 300 Xbox 360 games--including Red Dead Redemption and Call of Duty: Black Ops II--that don't require a second purchase.

At E3 2015, where and when Microsoft announced backwards compatibility support for Xbox One, PlayStation boss Shuhei Yoshida said Sony had no plans to offer a backwards compatibility solution of its own on PS4. "Backward compatibility is hard," Yoshida explained at the time. "I won't say we'll never do it, but it's not an easy thing to do. If it was easy we would have done that."
