"The free-to-play model is something we've been interested in since we first began working with Korean publishers four years ago," explained CEO Mark Long. "It's exploding in China, growing fast in Europe and emerging here in Facebook and iOS games." The new sales model will come along with the usual tropes one expects from a sequel, like gameplay tweaks and new weapons. Long says he hopes that the free model allows the studio to respond to player feedback quicker.

A publisher hasn't been announced, but the new model may complicate matters for console releases. The first game came to the Xbox 360 and PlayStation 3, but neither of the two consoles generally support free-to-play sales models. As a result, Blacklight might only come to the PC, but time will tell.
