Digimon Rumble Arena 2 (Digimon Battle Chronicle in Japan) is a Digimon fighting game released in 2004 by Bandai Games for the GameCube, PlayStation 2 and the Xbox. It is the sequel to Digimon Rumble Arena and has a similar style of gameplay as Super Smash Bros. Melee, except with a health meter. Digimon Rumble Arena leaps onto next generation platforms with a couple of new features. You can play as one of over 40 television characters in this fast and furious fighter. Battle your way through icy glaciers and across fields of fire in this digivolving contest of skills! The game features characters from the first four seasons of the anime (or Digimon Adventure, Digimon Adventure 02, Digimon Tamers, and Digimon Frontier in Japan). Each one has its own special moves and digivolutions, as well as slightly varying normal attacks and taunts.
