The Ecstasy Gauge is a new feature in No More Heroes 2: Desperate Struggle.
The Ecstasy Gauge represents the excitement and to lesser extent, ki, of Travis Touchdown. That excitement is boosted further when he attacks enemies and finishes them off, but decreases whenever Travis loses health. The Ecstasy Gauge can be boosted to max by grabbing a Sexy Magazine from chests.
It is represented by an 8-bit tiger in the lower right corner of the screen, which turns red in color as it rises into a ferocious stance, and also represents Dark Side Mode. As the gauge rises, Travis' strength increases, is capable of performing more attacks with his slash combos, and hitting faster and harder with beat combos. When the tiger glows white, which represents it is at its maximum, pressing the minus button (-) allows Travis to go into a super mode where it will allow him to perform an infinite amount of attacks and grant him super speed and invincibility.
The Beam Katana Peony is reliant on the Ecstasy Gauge for its range extension feature.
No matter how full or how filled it is, the Ecstasy Gauge will always drop to empty after a Super Mode or Dark Side Mode.
