Greenhouse Interactive has announced that its social networking SDK Nitrogen is now available for free to independent developers.
The Windows, Mac and Linux versions of the recently released Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness Episode Two will be the first indie title to implement the software.
“To the best of our knowledge, this is the first time anyone's offered these kinds of in-game reward and integrated community features on the Mac and Linux platforms," Greenhouse's Robert Khoo stated. “In fact, triumphs and standings are only the beginning. There's so much more in the works with Nitrogen that we just haven't found the vocabulary for yet. Stay tuned.”
Nitrogen allows developers to incorporate Greenhouse’s ‘triumph’ and ‘standings’ in-game awards for use on the firm’s playgreenhouse.com service.
