IncGamers' Chris Schilling has a hands on with the DS version of the movie tie-in.
From the preview:
As a game of a film of a Hasbro toy, you might reasonably expect GI Joe to be targeted at a fairly young audience. In which case, lines like "our new friends are nothing if not entrenched in symbolism" and talk of terrorist splinter cells would surely cause the odd quizzical look among the tween market. But when said movie has been described by its star (current hunk-for-hire Channing Tatum) as "a cross between X-Men, Transformers and Mission: Impossible", perhaps Joe is skewing a little older these days.
