Top Xbox Exclusive Boss Fights of All Time

RIFTWORM (GEARS OF WAR 2)

Technically, you never really fight the Riftworm itself. It swallows the Delta Squad whole, and they then have to make their way out of it. But while this may not be a boss fight in the traditional sense of the word, the set piece that sees Marcus and co destroying the Riftworm’s heart and then cutting their way out of this giant monstrosity is an unforgettable sequence.
