OnLive is touting their playable demo for Red Faction: Armageddon as a "PC/Mac exclusive," as apparently the cloud-based service will be the only place Windows and OS X gamers will get to sample Volition's upcoming shooter sequel (thanks Kotaku). Those with a free OnLive membership can access the demo through this page, where they also link to the offer they previously announced of a free OnLive console with preorders of the game through their service.
