The Floating Fortress (Smash Wars)

The Floating Fortress is the fifteenth stage in Rise of an Unleashed Army for Super Smash Bros. Smash Wars.

The level starts out inside a building, where demons are making weapons. The camera slowly zooms out to show that this building, this 'fortrees', if you would, is actually Midair Stadium, which has been 'demonified' since Kirby and his friends were forced to leave. The demons plans are delayed, however, as the Arbiter blasts his way into the facility, looking for any clues as to the whereabouts of Master Chief, who has disappeared.

He cuts down many demons as he fight through the former stadium, eventually reaching what the demons have been using to keep it alfloat: Cole MacGrath. Apparently, the demons have been using his powers of electricity to power the facility. The Arbiter frees Cole, and the two team up as more demons attack.

The two Smashers are more then a match for the demons, and they successfully escape the building. They then watch as Midair Stadium, now without power, falls and crashes into the ocean below. The two continue searching for Master Chief, while being watched by an unknown Smasher.
