The Grim Adventures of Billy and Mandy is a 3D fighting game based on the Cartoon Network animated series of the same name. Borrowing heavily from games like Power Stone, Billy and Mandy features frantic, often chaotic gameplay that's surprisingly fun for the first few hours. It doesn't take long to unlock all of the characters, stages, and game modes, though, and once you've done that you'll have a hard time feeling compelled to keep playing the game.
The gameplay in Billy and Mandy is simple. You choose one of the 15 playable characters and beat the living crap out of up to three other characters at a time. You have anywhere from one to four lives going into battle, and when you lose all of your lives you're out of the match. Each character has a weak attack and a slower, harder-to-pull-off strong attack. In addition, each character has a couple of special "mojo" attacks. As you fight you'll find and collect mojo balls, which fill up your mojo meter. Once it's full, you can perform a mojo smackdown, which is a series of attacks that automatically hit for heavy damage. If you fill up your mojo meter two times over, you can do a mojo meltdown attack. When you pull off a mojo meltdown the camera will zoom in on the action and a series of button icons will appear on the screen. If you press the corresponding buttons in time, you'll instantly kill your opponent. If you're playing the Wii version of the game, instead of pressing buttons you have to aim the Wii Remote at targets that randomly appear onscreen.
The combat isn't limited to simple melee exchanges and special attacks, though. Each stage is filled with items that you can pick up and throw, such as pumpkins, stones, basketballs, barbecue grills, and so on. There are also treasure chests scattered about that contain all kinds of weapons that you can pick up and use. There are ranged weapons such as the pane-o-glass gun, which (appropriately) fires panes of glass, a worm gun that shoots exploding grubs, and a laser-shooting scythe. There are also melee weapons like swords, hammers, and clubs. But wait, that's not all; there are also various traps and mounted weapons in each stage, so you can wait for your enemy to walk on a specific part of the floor before hitting a switch to make the floor electrified. Or, you can hop in a giant ballista and start shooting down your enemies from afar. All of the props in each level give you plenty of ways to go about beating up your enemies, and when you're playing with four players the action can get chaotic, which makes it difficult to tell what's actually going on at times.
All of the standard game modes are accounted for in Billy and Mandy. There's an extremely brief story mode that takes you through about half a dozen stages to face a weak boss. It only takes about 20 minutes to finish the story mode, so once you've played through it a number of times to unlock secret characters, outfits, and video clips, there's no reason to go back. You can also unlock all that stuff by completing the 45 missions in the game. The missions are all just battles with special objectives, such as to smash as many pumpkins as you can within three minutes. The missions are fun ways to unlock new characters, but they aren't especially difficult, and you'll probably be able to beat them all within a few hours.
There's also a versus mode in the game that lets you set up a fight to your own specifications. You can add up to three other computer-controlled characters, or up to three of your friends. There are several ways to battle, with eight different modes in all. There's the self-explanatory last man standing mode, as well as some fun and interesting alternate modes like bask-eye-ball, which requires you to grab a creature's eye, take it to a panel to change its color, and then throw it back into its socket to earn points. There's also a capture the flag type of game, a sudden death mode, and a mode where you earn coins for attacking your opponents and lose coins for being attacked. With a decent number of game modes and options to customize your fights, the versus mode offers the most flexibility and longevity of any mode in the game.
The presentation in Billy and Mandy is visually charming, but some minor technical problems occasionally get in the way. All of the stages are large and colorful, with themes like the underworld, an Egyptian tomb, a pumpkin patch, and a mad scientist's lab. The levels are large and very interactive, and they often change as your battles wage on. In one level, for instance, you start fighting on a rock platform in a pool of lava, but then a huge serpent swims up and you end up fighting on its back as it swims around. These touches make the stages much more exciting and interesting than they otherwise would be. The characters look bright and colorful, and they animate well. The problem is that you don't often get to see what's going on because the camera likes to zoom way out, and there are no indicators to highlight the characters on the screen so that you can tell each one from the myriad of other junk flying about the map. Also, the frame rate does tend to slow down a bit every once in a while. It doesn't occur often, but it's noticeable when it does.
The sound is appropriately goofy and over-the-top to match the style of the game. "Weird Al" Yankovic (UHF) provides the voice of the announcer and shouts things like, "Player one needs ham badly!" throughout each battle. The characters are all fully voiced, but they each have only a few lines of dialogue. Some characters speak in cutscenes, but all of the other characters have one battle phrase, one victory phrase, and that's about it.
The Grim Adventures of Billy and Mandy is easy to pick up and play, regardless of your familiarity with the license. It's a very basic brawler that does nothing to tamper with a proven formula, but it's still better than the average game based on a cartoon license. The versions of the game are all practically identical, so if you're looking for a new way to put the Wii Remote to use, you'll be disappointed with this game. On the other hand, that can be a benefit, because you can play the Wii version of the game with a GameCube controller if you're so inclined. That means that if you only have one Wii Remote, you can dig out your old GameCube controllers and still be able to get some multiplayer brawls in. Billy and Mandy is fun while it lasts, but unfortunately just doesn't have enough substance to keep you entertained for very long.
