Final Battle

Final Battle is the forty-second and last level in Metal Arms. Following their escape from the exploding Mil Space Station, Glitch and Zobby touch back down to Iron Star, landing in the middle of the debris pile that hit the surface of the planet. Glitch leaves the escape ship and begins surveying the area, only to discover that Corrosive had, indeed, survived the descent back to Iron Star. With the Mil General now damaged, Glitch take this opportunity to bring down Corrosive once and for all. There are four Secret Chips in this level.

Trivia
• Though only ever appearing in static form, this level is one of very few to depict red Grunts with Mining Lasers.

• If Glitch climbs and jumps around the level, he can reach areas of the Space Station he once explored, most notably the hanger area in the level One Small Step. The scale of the hanger, however, is much smaller than how it appeared prior, though it most likely wasn't intended for Glitch to be able to reach it, but to instead see it from afar and treat it like a distant piece of debris.

• The Rocket Glitch and Zobby use to escape cannot be destroyed by Glitch or Corrosive.

• An ability unique to this level, Corrosive can summon Troopers from his body to aid him in combat.

• These Troopers appear to function as a sort of hivemind, with Corrosive maintaining control over them. Besides not having any personalities of their own, Corrosive is capable of destroying them at will, without targeting them directly. Though, the Troopers can both be manipulated and used by Glitch, by usage of the Control Tether and by using Recruiter Grenades. Furthermore, upon Corrosive's defeat, any remaining Troopers will be destroyed along with him.

• Although this level concludes the released story of Metal Arms, this was originally the ending of the first part of an intended trilogy. See here for more.
