"Rebirth" uses the "Tales" series' trademark Linear Motion Battle System (LMBS), a real-time fighting system similar to a beat 'em up. Up to four characters can be present in battle. The variation used in "Rebirth" is the Three-Line LMBS, using a similar multi-plane mechanic to "Tales of Symphonia": characters can be moved across three different levels on the battlefield to either attack enemies on those lines or dodge behind an enemy on one line to deal damage from behind. During battle, a character can activate the Rush Gauge, increasing a character's attack power at the cost of lowered defensive abilities and stats, and perform with another member of the party to inflict high damage on single enemies. During battles, performing certain feats in battle, such as finishing in a certain time, rewards the player with a grade for their performance.
