Despite a long-term disappearance (perhaps into the bowels of the Earth?), Ubisoft's I Am Alive will arrive on consoles via Xbox Live and PlayStation Network, confirming previous suspicions. The game is said to arrive at some point "this winter."
Following the story of a yet-to-be-named "everyman," Ubisoft Shanghai's I Am Alive is a digital romp through a city (Chicago, last we saw) that has undergone a devastating catastrophe. Resultantly, said everyman must fight for survival against the elements as well as various other people, all the while attempting to find his wife and daughter.
Combat is said to be based on intimidation more than brute force (briefly demonstrated in the original announce teaser). We'll presumably have more info for you soon, as Ubisoft finally seems ready to talk about the game once again.
Update: Ubisoft confirmed with Joystiq that there are currently no plans for a PC version of I Am Alive.
