Viewtiful Joe: Red Hot Rumble is a melee fighter in the vein of
Super Smash Bros. In each battle, up to four characters will face off on the screen trying to either deal out more damage than the other players, collect more money or orbs than the other players, destroy more Bianys and Flatys (the grunt soldiers of the game) than other fighters, or achieve many other different win-conditions that are more than just the standard "fight until you die" situation found in most games.
Red Hot Rumble's story modes follow each of the series' main characters. You can play as Joe, Captain Blue Jr., Blade Master Alastor, Sexy Silvia and several other unlockable characters as they each try and claim a starring role in Captain Blue's next action movie.
Each fight is to be a part of the new movie. So scenes will include Joe fighting his rival, Alastor, on the roof tops and then the two need to take down Emperor Jet Black's helicopter. Or a fight might take place on a bi-plane's wings as Drill Sergeant Big John attempts to shoot you down. All the while, various items either get dropped by opponents or appear on the screen that can be used to either enhance your health or deal out more damage (once again in a very Smash Bros style).
Besides the story mode, Viewtiful Joe: Red Hot Rumble also features Battle Mode. Here four players can get together and duke it out. You can go up against either three other humans or up to three A.I. controlled opponents. I will say that trying to fight with four people going all out on the screen can get a bit unnerving. I found it hard to keep track of which character I was and it felt like there was way too much action going on in order to perform well.
Why does this work for Super Smash Bros and not Red Hot Rumble? This game is just way too flashy and the characters are too big. Smash Bros typically has huge arenas and a camera system that zooms in or out in order to keep all of the fighters on the screen, and those characters don't typically take up a lot of screen space. Such is not the case here. Typically, the characters in Viewtiful Joe are large and take up a lot of real-estate. Between four characters jumping around and explosions going off every time you turn around, it is just too hard at times to keep track of who you are and what you are trying to do.
