I'm not sure how I missed this. It's been up since Sept a year ago. But, for those who may be interested, here's the link:
http://www.gamershell.com/download_20867.shtml EDIT/NOTE: I've found a few posts from a year ago stating that this particular 'free' game is actually a 'trial' version. I have about 20 minutes left on my download and will see what's what with it. There are also some notes that state that it isn't supported for non-USA players. Some of those have posted that, simply setting up your PC for "USA" will make it work.
Updates later.
EDIT/UPDATE: This one can be tossed in the trash! During the installation it prompts for a UBI username and password. I can't believe it's still available for download as a 'free' game.
FINAL EDIT: It helps to scroll down to read ALL of the Instructions. Here's what is posted 'below the line'
"You will need an Ubi.com account and you must live in the U.S. to play the game
Update:
The promotion is now closed and it is no longer possible to play the game for free. If you are interested in further information on this title, visit the Ubi official website at http://www.ubi.com/"
