30-second TL;DR

Adventure Guide says

  • Mimiron engages his enemies with inventions rather than directly in combat.
  • The Leviathan MK II is a deadly vehicle that assaults the Tank with powerful attacks, the VX-001 which strikes enemies with rocket blasts and laser barrages, the Aerial Command Unit which engages enemies from the skies, and finally the V0-L7R-0N unit, which combines the might of all of his inventions.
  • Stages named in the Adventure Guide: Stage One: Leviathan Mk II, Stage Two: VX-001, Stage Three: Aerial Command Unit, Magnetic Core, Stage Four: V0-L7R-0N, Hard Mode, Stage One: Leviathan Mk II, Stage Two: VX-001, Stage Three: Aerial Command Unit, Stage Four: V-07-TR-0N.
  • Tanks: Prepare for heavy damage when the Leviathan Mk II casts Plasma Blast.
  • Healers: Be spread apart to avoid the Leviathan Mk II's Napalm Shell.
  • Damage dealers: Avoid the Leviathan Mk II's Proximity Mines when fleeing from Shock Blast.
