Whacked! is among the first batch of Xbox games to support the Xbox Live service. It includes all the standard Xbox Live features, including voice masking and various forms of player matching. It's easy to get into a game and get going, and the game rarely shows any noticeable signs of lag. Of course, not many are playing Whacked! at this time, since the Xbox Live service isn't fully available yet.
The game has a stylized look to it, rendering all the different characters in some form of the "twisted versions of your typical cartoon character" motif. The game's cutscenes are the best place to see the characters in action, as the rest of the game moves too quickly for you to get a sense of the visuals. The game's prerendered cutscenes and commercials are probably the sharpest part of the entire game. The commercials, mostly drawn in a crude, scribbled style, are genuinely funny at times, particularly the public service announcement that warns you not to shoot fire at police cars. The game's levels are colorful and showcase some pretty good texture variety from stage to stage, and the frame rate is constantly smooth, which is a nice touch, though perhaps an expected one, given the simple design of the characters and the game's small environments.
The multiplayer mode has its moments, but the single-player mode is way too easy.
Though Whacked! looks good, the game's soundtrack is mostly annoying. The character voices fit the contestants pretty well, but the soundtrack is grating in a way that only bad cartoon music can be. The game's sound effects are your standard cartoon-style effects, complete with boinks, whoops, and various explosions.
Whacked's main problem is that there simply isn't much to it. The single-player mode is plain and simple, and the multiplayer mode, once you get over the novelty of shooting people over the Internet, really lacks depth. It benefits from being the first action game with Xbox Live support, but considering the fact that other, deeper action titles are slated for release when the service officially launches next month, anyone who isn't an Xbox Live beta tester desperate for something other than a sports game should really look elsewhere.
