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.

Touch Screen
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. 6 for Zemerl (the first 5 are 10% each).

New Mechanics
On level 0 the player can perform a Lvl 1 Special Move (Zemerl can only perform this with a cost per bar), on level 1 the player can perform a Super Special, finally, on level 3, the player can perform either a Team Special, which requires 1 or 2 teammate(s) to activate, or activate Super Form (only if no teammates are present). Both the Super Special and the Team Special requires making contact with a foe (or also rush into them) in order for it to activate. The game also has an option in the Options mode called Classic Specials (ON/OFF) which turns the Special Gauge into the one from the original Sonic Battle game. When at full the characters start to flash as well as their icon and gauge, and the Special Moves that hit any characters will instantly KO them, but only works once per full gauge, hit or miss.

Zemerl, unfortunately, is unable to use a Super Form (excluding Omega Zemerl who is exclusively as a final boss) or 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 since it can cause an imitiate Game Over in 1 hit) or "Combo" Data Cards obtained from approaching the SONICTEAM billboard.

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 (and possibly the official reviewers), 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.
 * Finale is named after an ability from the "The End" Garment Grid in Final Fantasy X-2.
 * Also, Omega Finale, Omega Zemerl's Super Special, is named after an ability exclusive to Sora's Valor Form in Kingdom Hearts II.
