The only way to beat the giant Beta is via direct attack to the brain, forcing Ogre into a very perilous situation. Auctioneer risks his life to locate the brain, and Ogre uses Number 11 to take it out and defeat Beta.

He reunites with the Squad and celebrates, but his joy would be short-lived.
Go face all the people you killed!
!فلتتلقَ أصوات كلّ الأشخاص الذين قتلتهم حتّى الآن
Mach dich gefasst, dich all denjenigen
zu stellen, die du auf dem Gewissen hast!
¡Escucha las voces
de todos a los que asesinaste!
¡Escucha las voces
de todos a los que asesinaste!
C’est la voix de tous ceux
que tu as tués jusqu’ici !
Affronta le voci delle persone che finora
Vá encarar todas as pessoas
que você matou!
Иди и посмотри в глаза всем тем,
кого ты убил! Исчезни!
