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.
Sorry, we were split up 
right after Beta ate us. I'm alone now.
آسف، انفصلنا بعدما اُبتلعنا، وأنا بمفردي الآن
Tut mir leid, wir wurden getrennt, als er uns
gefressen hat. Nur ich hab es rausgeschafft.
Lo siento. Nos separamos
cuando nos engulló.
Lo siento. Nos separamos
cuando nos engulló.
Désolé,
on a été séparés à l’intérieur.
Scusate...
Desculpem, nos separamos assim
que fomos engolidos. Estou sozinho.
Мне жаль... Когда Бета проглотил нас,
мы разделились, и теперь я один.
