Inward Chaos is a storyline in Dissidia Final Fantasy. In the original Japanese version, it is unlocked after defeating Chaos for the first time in Shade Impulse. In the North American, European and Universal Tuning versions, it is unlocked after beating all other storylines. It is the hardest storyline in the game, pitting the player against a gauntlet of the twenty-two playable characters with levels eventually exceeding 100, culminating with a fight against Chaos at Level 110. The player is advised to have their chosen character at Level 100 with high-level equipment and several powerful summons before attempting to complete this storyline.
