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.
You died for nothing.
متّ بلا معنى في النهاية
Letztendlich bist du für nichts gestorben.
Pero tu muerte será en vano.
Pero tu muerte será en vano.
En fin de compte,
t’es mort pour rien.
In fin dei conti, sei morto invano.
No final, morreu por nada.
Твоя смерть была напрасной.
