Death Machine is an enemy exclusive to the PSP version of Final Fantasy IV: The After Years. It appears as a rare enemy in the Lunarians' Challenge Dungeons, and always occurs in a formation consisting of itself, a Mythril Golem and a Steel Golem. Should the Golems be defeated, it will retaliate with Meltdown, which, being based on the user's current HP, will almost certainly kill the party; it is therefore recommended to dispatch of it first with a Break or Death spell.
Killing Death Machine will guaranteed to reward one of its item drops.
