BlazBlue: Continuum Shift Extend (originally titled BlazBlue: Continuum Shift II Plus) was released on May 31, 2012 in Japan for Playstation Portable.
During each rebel, players fill a Heat Gauge which can be used for advanced techniques such as Distortion Drives, Rapid Cancels, Counter Assaults, and certain characters' attacks (Jin/Hakumen). The Heat Gauge can be filled via dealing damage, taking damage, and perfectly blocking attacks. However, some mechanics from the previous installment have been changed or completely replaced in the transition.
