Fire It Up

Fire It Up is the twenty-second level of Metal Arms. In this level, you play as Slosh.

After being rescued by Glitch, Slosh offers to aid the Droid in powering up the lift that'll take him to Mil City. In order to do that, Slosh must go on his own journey deeper into Mil and Swarmer populated areas.

Trivia

 * Despite evidently being fearful and panicked by the Morbot Region, Slosh is oddly enough willing to step into danger once more. Though it is possible Slosh was inspired by the thought of finally being able to leave the Morbot Region and garnered the strength to fight once more.
 * Because this is the last level to take place in the Morbot Region, this level marks the final appearance of the Swarmers.
 * In the beginning of the closing cutscene, Glitch can briefly be seen with a Level 1 or 2 Rivet Gun, even if he is in possession of a Level 3, which has a visible rotating barrel.
 * Upon completion of this level, Slosh gives Glitch his Toaster. If all primary weapons up until to this point have been collected, then this fully completes Glitch's primary loadout.

Cut Content
In the previous level, Slosh mentions the existence of a big, mean Swarmer in the reactor. However, as Slosh ventures through the reactor, no such Swarmer is present. This Swarmer, known as the Swarmer Boss, was a piece of cut material that failed to be implemented, due to the lack of time to implement its AI.
