This was a tie-in effort with the (comically bad) live action Gundam film of the same name. The game itself isn't that bad though but it does look pretty dated.
The game is very linear but movement within the levels is fairly open. You have two types of control, normal and hover. Hover mode allows you to move much quicker and evade enemy weapons fire with greater ease.
Bizarrely, the developer who made this game (Atelier Sai) now make toys. Go figure.
