Graphically, Army Men: Advance foregoes the usual Army Men style in favor of a more humorous, cartoon-like approach. This adds a real charm to the game as a whole, and is pulled off rather nicely, but they are also very lacking in detail and come off as being average when compared to the other GBA launch games. Many of the areas are very simple and you will find yourself walking through barren one-colored fields for most of your mission.
There's really nothing to this game in the sound department because, except for the title screen, there is no music. I found this very disappointing considering the excellent title screen music (and yes, it does sound just like the Hogan's Heroes theme). The sound effects are also passable, with just the typical grunts, gunshots, and explosions.
