The publisher has "nothing to announce" on the game right now. Apparently it will be releasing only for Xbox Live Arcade and PlayStation Network.
"We haven't announced anything and we have nothing to announce at this time," said Ubisoft in response to the rumours. I Am Alive was announced back in July 2008 at E3 but since then went underground - it was labelled as an innovative action thriller.
Our character was a survivor of a massive earthquake to strike Chicago, decimating the urban landscape and leaving us stranded and fighting to survive.
