I Am Alive is no longer coming to Windows PCs, we learned today after receiving an announcement from Ubisoft today saying the post-apocalyptic action/adventure will arrive for Xbox LIVE Arcade and the PlayStation Network this winter. This follows a rocky development cycle that involved a delay, a switch in developers from Darkworks to Ubisoft Shanghai, followed by another delay and yet another. The game was first thought to be a console title, but Ubisoft later announced it would be coming to PCs as well, something that seemed to be confirmed as recently as three days ago, when an ESRB rating for I Am Alive was discovered, listing platforms as "Windows PC, PlayStation 3, Xbox 360." We contacted Ubisoft to ask why the PC edition was not mentioned in today's announcement, and were told, simply: "There will be no PC SKU for I Am Alive."
