Metal Arms: Glitch in the System/The Zombiebot King
From SDA Knowledge Base
First boss battle.
Rocket Launcher ammo is behind your spawn. SPEW, Rivet, and Scatterblaster ammo are along the far wall.
The first grate on your left contains a Fleet Foot booster, which makes this boss a lot easier to manage.
After defeating the boss, Mozer gives you the level 2 rivet gun.
