God Eater 2 Rage Burst is an enhanced version of God Eater 2, adding new features and elements to the game. A new chapter titled "Rage Burst" is added to the story, featuring content separated into six difficulty levels within the main quests. Rage Burst introduces a new game mechanism known as "Blood Rage", which involves filling an Awakening Gauge by attacking enemies, and then making a pledge to the God Arc once it activates, granting various buffs to the player.

Temporary invincibility can be toggled during the pledge selection process, at the expense of draining the Awakening gauge. The game also introduces new characters, enemies and weapon types.
