LRFFXIII - Lightspeed

Lightning using Overclock.

Press L2/Left trigger in battle to slow the world's time to a crawl, allowing only Lightning to move normally.

Overclock (オーバークロック, Ōbakurokku?, lit. Overclocking) (also identified as Lightspeed on the official page[1]) is a battle element in Lightning Returns: Final Fantasy XIII where Lightning can slow time around her while she moves at normal speed.


When the player unleashes Overclock with L2/Left trigger, the ATB gauge is replaced by the Overclock gauge, which is, in fact, the usual ATB gauge. Overclock slows time for enemies while Lightning operates at full speed. For example, if the ATB is 150, and the player has an attack that consumes 30 ATB, when they activate Overclock they'll be able to use this attack 5 times (30 ATB x 5 = 150 ATB) before the Overclock gauge is depleted each attack consuming a fifth (30/150 is 1/5) of the Overclock gauge. Lightning can execute abilities not normally executable due to insufficient ATB points. For example, executing Beat Down Lv. 1 with 50 ATB points cost is possible during Overclock with 49 ATB points or fewer, but after its execution the Overclock will end. When the Overclock gauge is empty, the player resumes normal control of Lightning, and she has full ATB on all the three schemata.

Pressing L2/Left trigger again while in Overclock unleashes Lightning's special attack, Army of One.

Overclock is activated through Energy Points, requiring 1 EP on Easy Mode and 2 EP on Normal and Hard Modes each use.



Overclock concept in Final Fantasy XIII; the image for the similar gameplay mechanic appears in the top right hand corner.

Overclock was originally envisioned to reduce the time limit Lightning has until the end of the world, but the two systems were separated to prevent player hesitation in utilizing the system.

When making the announcement trailer of Final Fantasy XIII, a concept of the Overclock system was used in the battle system demo. In fact, no battle system had yet been designed for Final Fantasy XIII at this point, and the trailer was merely a visual demo for the feel of the game the developers wanted to portray. It appears, however, that the demo was the direct influence in developing the Overclock system for Lightning Returns: Final Fantasy XIII.

Musical themesEdit

A track called "Overclock" appears in the game's original soundtrack as a fifteenth track on the third disc. It plays simultaneously with the currently played track whenever Lightning unleashes Overclock.


Overclocking is the process of making a computer or component operate faster than the clock frequency specified by the manufacturer by modifying system parameters (hence the name "overclocking").
