"There are some important caveats about this free version of the game which should be disclosed but aren't by any of the websites like Filefront which are distributing it. First, this release of the game has Double Fusion's advertising and tracking software embedded in it. Second, even though this is a single-player game, it always requires an active Internet connection to play. There is no offline play. Third, the game can't be played from just any country (IP address). I'm not certain if it is just limited to U.S. IP addresses or not, but there is an error message screen that notes that the game isn't playable in some countries. Finally, the ability to play this game may be terminated at some point in the future by the publisher. Similar free games supported by the same advertising and activation scheme released in the recent past have already had their "plugs pulled." So if you want to play the game, do it soon."
A filefront comment worth noting.
But still, thanks, Im going to DL it anyways (looks like a decent game)
