The first Project: Snowblind was a FPS released for the Xbox and PlayStation 2 in 2005. It was originally conceived as a multiplayer-focused third game in the Deus Ex series, Deus Ex: Clan Wars. But after the less than expected commercial performance of Deus Ex: Invisible War, it was decided to set the game in its own universe. Nevertheless, it remains a spiritual sequel to Deus Ex and retains many visible and conceptual links to its progenitors. [Infos from Wikipedia]
The sequel, Project Snowblind 2, was in development at Crystal Dynamics, but it was later cancelled for unknow reasons (maybe for the low-sales of the first game?). The game was set in a city many years after a devastating invasion force had reduced it to a post-apocalyptic state. Only few concept arts remain for this project.
