The overall art style of Rise of Sin Tzu mirrors the highly stylized art deco look of the recent Batman cartoons, creating a dark, brooding atmosphere, while remaining fairly kid-friendly. Character designs are exaggerated, with square, Dick Tracy-style jaws and big, barrel chests being the most common traits. Animations are also exaggerated, giving a big boost of comic book bravado to Batman's punches and kicks. You'll encounter fewer than a dozen different types of enemies through the course of the game, but tweaked character models and different textured skins help keep their appearances fresh. Light and shadow play big parts in the graphical presentation, and all of the lighting effects in the game look great. Shadows will stretch, depending on their distance from the light source, lights will give off a little lens flare when viewed directly, and glossy surfaces will reflect light accordingly. There are plenty of cool particle effects too, most notably in the game's convincing explosions. The volumetric fog that creeps out of the alleys of Gotham City just looks great as well. Though the scope of the game is pretty tightly focused, not really giving you a big picture perspective of Gotham City, it still looks really great. The only complaint that can be lodged against the visuals is the fully automatic camera, which usually helps keep the action square in front of you but can occasionally be a touch disorienting.
The regular introduction of new moves helps keep the gameplay fresh, and the occasional boss fight helps stave off monotony.
The sound design in Rise of Sin Tzu stands up as well. Attacks register with a pleasing amount of force, further amplifying the already heightened, comic-book level of punishment the thugs are taking. All of the voice acting, which is provided by the actors from the Batman cartoons, is top-notch, despite the fact that some of the dialog can be a bit melodramatic and rife with metaphors. In an odd style choice, the soundtrack in Rise of Sin Tzu is largely dominated by stripped-down three-piece rock music, though some dancey electronic stuff occasionally comes up as well. It's actually pretty good music, but it just doesn't quite fit the overall feel of the game.
The simplicity of the gameplay in Batman: Rise of Sin Tzu is one of its biggest strengths and one of its biggest weaknesses. If constantly slugging it out with common street toughs for a few hours doesn't sound appealing, this probably isn't the game for you. But if you do enjoy straightforward, no-nonsense action, Rise of Sin Tzu delivers it in an appealing package and is one of the best 3D beat-'em-up action games you'll find.
