Graphics have never been a hallmark of the Army Men line, and Air Combat continues the tradition. The tagline for the series has always been 'Real Combat. Plastic Men.' The soldiers certainly look plastic, but so does everything else - even some of the items that aren't plastic, like gloves, apples, and baseball caps. For example, when you pick up a glove with your winch, you would expect it to droop a little (unless, of course, it's been sitting in the back alley of your Rockingham Estate). While this could certainly be attributed to the lack of physics in the Army Men universe (which is something I'll get into later), it came off as laziness.
Another sticky issue was the game's lack of scale. Since you're taking on the role of a toy, it's understandable that everything would be bigger than you. This is one of the more enjoyable aspects of the game. However, many of the things in Air Combat just don't match up. A prime example of this would be the missile-shooting dogs (yeah, I typed that right) that are smaller than their food bowl. To be more exact, they could fit in the food bowl. There are a few more instances of this that occur in the game, but why kick someone when they're down?
The soundtrack is your typical Army Men fare. Most of the in-game music is good and fits the style, but some of the other tracks (like the 'Mission Compete' score) are weak. The voice work is good, and is likely the most enjoyable part of the game. As with Army Men: RTS, it was great to see the influences of old war movies in the game's dialog. Although, it wouldn't be a bad idea to start finding some new movies to quote, since you can only hear 'I love the smell of plastic in the morning' so many times before it gets old.
