Though it hasn't been officially announced yet, this Sanity Aiken's Artifact page has the debut release of the Sanity demo, a playable version of Monolith's LithTech-engine strategy game. The demo offers two single-player and two multiplayer levels, and we can expect more details when an announcement comes down, but for now it can be downloaded for the price of a Real registration (there is a seven day exclusive on the downloads).
