A Finisher is a powerful move that Hayden can perform when an enemy is sufficiently damaged, manages to get behind an enemy, or when Hayden is Shifting. When executing it, the enemy is brutally mutilated and usually killed, except in the case of Bosses. When an enemy is glowing red, a finisher can be performed without Shifting, and this is generally required to defeat most bosses.
Finishers vary from enemy to enemy, but they generally involve the application of the Glaive to cranial areas or the breaking of necks. Getting enemies from behind usually results in Hayden breaking the target's neck.
