I'm not a crazy Transformers fan. As a kid I grew up watching them occasionally. I did like the movie and the Wii game so I decided to add to my DS collection. Since the game was released prior to the movie, it varies from the storyline slightly. (Which is fine because sometimes you think you know what's coming and you're way off.) The gameplay is pretty fun and I like being able to scan vehicles, which you can transform back into anytime during the game (except for some missions). BIG PROBLEM: In each version there is a jet that you see but cannot scan. There is a jet transformation that you can use but it seems impossible to get now. You have to take your DS with your version of Transformers to a DS download station (here's where it gets hard) in a Target that has that same version for download. Once you download the demo with your Autobots game in... you have the jet. Problem is: Most DS download stations only have newer games. This game is not new.There is a POSSIBLE solutions for those of you who have a Wii. On the Nintendo Channel you can download demos for your DS. If they were to release Transformers demos to the Nintendo Channel then simply download from there. I don't think that is very likely though.My final suggestion: get the game, enjoy it, and get really good at using the stealth helicopter transformation because you're not getting the jet.
