Overview

Tentatively *Polymephycite tympanum*. Not animal, plant, or fungus, but a fourth category of complex life analogous to Earth protists. As passive fauna, False Fission Drum coexists peacefully with divers. These organisms are often the first new players encounter and scan, building PDA knowledge before deeper exploration begins. Cataloging False Fission Drum contributes to your PDA's ecological model of the local region. The database cross-references scanning data to identify predator-prey relationships, territory boundaries, and migration corridors. Comprehensive PDA scanning of all species including False Fission Drum unlocks the full value of Subnautica 2's data system. Cross-referenced entries reveal ecological connections, resource chains, and behavioral predictions that casual players never discover.

Tips & Strategy

Central structure: The central stipe is a biopolymer akin to chitin or keratin held upright by a beard of air-filled sacs (pneumatocysts).

Dual feeding strategy: Photosynthesis is the primary nutrient source, but cave-dwelling drums subsist on dissolved nutrients.

Reactor glow: Adults develop a large bioluminescent swelling called a sprangia. Its blue light precisely mimics the Cherenkov radiation of a nuclear fission reactor immersed in seawater. Assessment: further investigation required. Await further updates.

Passive fauna like False Fission Drum react to predator proximity before you can see the threat. Watch for sudden directional changes or schooling behavior as an early warning system.

In multiplayer sessions, use False Fission Drum's location as a shared reference point when coordinating exploration routes with teammates.
