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.
Don't worry. I was created 
for the sole purpose of destroying Beta.
لا تقلق، صُنعت بهدف هزيمة بيتا لا أكثر
Mach dir keine Gedanken, ich wurde nur zu
einem Zweck erschaffen: Um Beta zu vernichten.
No te preocupes. Nací únicamente
para derrotar a Beta.

Не думай об этом. Меня создали
исключительно ради уничтожения Беты.
