Digimon Rumble Arena 2 is a fighting game for the Sony PlayStation 2 that was released in the United States. The title expands upon its predecessor by adding a larger roster of more than forty characters drawn from the Digimon animated series. Players can choose from a diverse cast that includes both rookie and champion forms and can watch their Digimon digivolve mid battle to gain new powers. The combat system is fast paced and emphasizes combo chains and special attacks that can be executed with simple controller inputs. The game also includes a training mode that lets new players practice combos and learn the timing of digivolution moves. Each character has a unique set of attacks that reflect their personality and abilities from the original series. The arena designs are not only visual but also affect the flow of battle with environmental hazards that can be used strategically. The game offers several arena types such as icy glacier fields and fiery battlefields that provide visual variety and strategic differences. Multiplayer mode allows two players to duel locally using a split screen or online connection. The graphics engine renders detailed sprite work and smooth animation that take advantage of the PlayStation 2 hardware capabilities. The soundtrack features energetic music that matches the intensity of the fights. The game was added to the iOctavio.com website on June 18 2005. Although the game is fundamentally a fighting title it was originally categorized under Card Battle which may have caused confusion for users searching for the correct genre.
