How to Unlock

You must place three C4 charges on each of the zombie guts piles on the center platform of the Mars area and gather a horde of zombies onto the platform and detonate all the C4 killing the horde. If done correctly, you'll hear Mister Peeks laugh and the relic trial portal will appear in the Machina Astralis. This relic's trial is: Enemies can only be killed while using a Field Upgrade.

It is currently unknown how many zombies specifically you need to kill on the platform with a single detonation, but a single horde should be more than enough.
