Transformers DS review at Aussie-Nintendo.
"By now, most of you reading this would have watched the movie at least once. Long time fans of the cartoon series, myself included, have been waiting eons for a live action movie, and what we have showing in the cinemas now is surely what we were waiting for. So how do the video game tie-ins stack up?
Transformers video games have been around since the 1980's. 1UP has an interesting article about these called "Robots in Disgust". We have 2 separate games on the DS; Transformers: Autobots and Transformers: Decepticons. Each one has their own playable characters and loosely follows the movie's storyline."
