Atmosphir is a gaming platform and engine that allows users to easily create their own levels in a 3D world by painting basic elements into a three dimensional grid. After downloading a client application, users can play in their own levels, or they can visit the Atmosphir community website to play on any of the maps that have been uploaded by other users. The application is currently available in a limited beta with plans to release by the end of the year, and is available for both Mac and PC.
