The development of I Am Alive is a long story. The Darkworks-envisioned title was first prototyped around 2001. In 2006, after Cold Fear was released, Ubisoft picked up the title. At E3 2008, it was officially unveiled with a CGI trailer.
In March 2009, Darkwork's version was meant to be released three months later at that time, Ubisoft took the game away from the Paris studio and put Ubisoft Shanghai on it. Ubisoft Shanghai was meant to "repair" the game, adding multiplayer and other features. Thus the game was a no-show in 2009.
At E3 2010, Ubisoft showed a new trailer of I Am Alive. What they didn't say at that time, it was an incredibly old trailer, dating back to early 2009. In fact, it was produced at Darkworks, and as Ubisoft couldn't ask them to remove their logo from the trailer at the end, they simply cut off the trailer's ending, blending in a black screen with text.

A few months later, the game was started from scratch, only to be released a year later as a XBLA/PSN title.
