Sonic Battle Overdrive

Sonic Battle Overdrive (ソニックロックンランブルSonikkurokkunranburu, lit. Sonic Rock 'n Rumble in Japan), known as Sonic Battle 2 in Europe, is the sequal to Sonic Battle. Exclusive for the Nintendo 3DS.

Gameplay
Sonic Rock 'n Rumble is the same as it's prequal, but with upgraded and updated gameplay.

The Touch Screen allows the player to see the current Vitality and Special Gauge of its teammate(s). The Touch Screen also shows a Special Move that can be performed while on a certain level of the Special Gauge, which is 2, 3 for Zemerl.

On level 0 (1) shows the player can perform a Lvl 1 Special Move (Zemerl can only perform this with a cost per bar), on level 1 (2) the player can perform a Super Special, finally, on level 3, the player can perform a Team Special, which requires 1 or 2 teammate(s) to activate. Both the Super Special and the Team Special requires making contact with a foe in order for it to activate. Zemerl, unfortunately, is unable to participate in any kind of Team Special and can only use his own Super Special, which is Finale (though during his Omega form his Super Special is turned to Omega Finale, which is stronger than a Team Special.

The game also introduces the ability to go head-to-head wirelessly or on the internet. Like Mario Kart Wii/7, chosen (or voted) stages will be selected randomly.

Trivia

 * Zemerl's name was originally intended to be called Xemerl with the first letter resembling/based on Sonic X, but because of the show's poor critisism by the fans, it was later changed to Zemerl (with the first letter similar to Dragon Ball Z!).
 * Challenge Mode has been changed to Arcade Mode, with differed mechanics as well.
