Here's the story so far
Electronic Arts and Visceral Games have announced that a demo for Dead Space 3 will be dropping on Xbox Live and PlayStation Network on January 22, 2012, giving us a couple short weeks before the horror game's full release on February 5.
Those who want to nab it a week earlier can do so by registering their Origin ID for an early-access code redeemable for the Xbox 360 demo. And speaking of Origin, there's been no mention of a possible PC demo, so don't hold your breath for that.
The video embedded above is a well-made, no-nonsense recap of the Dead Space story so far. Even if you've played both main-series games, it's still a good refresher. You might even learn a thing or two.
