According to Ninja Theory co-founder Tameem Antoniades, the studio's PS3 exclusive Heavenly Sword didn't sell well enough to turn a profit, leading the studio to broaden its potential market by turning multi-platform.

"It's difficult. Heavenly Sword came out pretty early on the PS3, and we sold, I think, a million and a half copies, and that's still not enough as an independent studio to break even,"Antoniades told CVG.

"The publisher potentially breaks even at that point, but the developers don't."

The large installed base of the Xbox 360 made it a platform impossible to ignore, explained Antoniades.

"It's just that when so many people have Xbox - I mean over half the market or more has Xbox 360s - why limit yourself to one platform?" he said.

Ninja Theory's Enslaved is scheduled for release in the autumn for PS3 and Xbox 360.
