Like most kart-racing games, Freaky Flyers has a collection of power-ups scattered throughout its courses. Picking one up gives you one of several random items, such as missiles, floating mines, homing missiles, shields, or a sort of energy discharge that damages nearby opponents. You also have access to a machine gun that has infinite ammunition but can be fired for only a few seconds at a time. With its sustained fire, the machine gun does a decent amount of damage to opposing flyers, but its main purpose is to interact with the world for the completion of mission goals.
The game's races are three-lap affairs that take you through a variety of themed courses.
Perhaps the biggest criticism to be levied against Freaky Flyers is that it's incredibly straightforward. The game is slow to the point of feeling sluggish, and overall, there really isn't that much to do beyond slowly chugging around the course, firing off weapons at the other flyers, who don't put up much of a fight. Even though the genre doesn't typically deliver a three-dimensional flying experience, Freaky Flyers just doesn't play better or really all that different from many other, similar games.
Graphically, Freaky Flyers looks OK. The racers are drawn in a larger-than-life sort of cartoon style that works well with the subject matter, and the environments are pretty big. However, none of it looks particularly great. The PlayStation 2 version has the added drag of an unstable frame rate, which makes the game's larger areas jerk and skip along. The Xbox version doesn't have this problem, and it also has the benefit of looking slightly cleaner, as most Xbox ports tend to do.
The audio in Freaky Flyers is all over the place. The character voices and the ever-present announcer contribute to the cartoonlike presentation, but again, the repetitive nature of the racers' in-race speech is disappointing. The game's soundtrack covers a lot of ground and has a lot of original music that fits the game's personality, including some pretty crazy songs to accompany the minigames that have lyrics that basically describe what the minigame is all about.
All in all, Freaky Flyers has some enjoyable moments, but the course design and weapon selection are pretty standard. It's definitely worth renting if you're a fan of the genre.
