First of all, they have made public today that the Unigine Engine is powering Cradle. Cradle is "a science-fiction first-person quest with freedom of movement. The story is built around the relations of the protagonist and a mechanized girl, who by enigmatic circumstances find themselves together in a yurt among the desert Mongolian hills. The player is to restore the lost functions of his companion's mechanical body parts and together reveal the mystery of the neglected entertainment park found not far from the yurt."
The Unigine-powered Cradle is expected to be out in spring of 2012. There's no word on the state of a Linux port, but hopefully it will be there thanks to Unigine's multi-platform goodness. The screenshots shown in the press release and the official trailer (embedded below) are impressive.
Unigine has also announced some engine updates to end out the year. The SSDO blur filter has been optimized, there's improved quality of HDR and glow, detection of Radeon HD 7000 series GPUs and Intel GUs, two separate reflect colors for water, particle improvements, mobile shader improvements, improved physics, and major additions to the Unigine C++ API.
