In RimWorld: Odyssey, the **Mechhive** represents a pivotal orbital endgame mission where players can eradicate the mechanoid menace for good. Conquering this fortress lets you either purge all mechanoids from the planet or harness their energy, permanently altering your game world and unlocking a unique post-campaign state.
What Is the Mechhive (Mechanoid Hive)
This colossal frozen station in orbit serves as the mechanoids’ production hub. Protected by advanced defenses, dormant war machines, and automated security systems, it coordinates all mechanoid raids across the planet.
How to Unlock the Mechhive Mission
Access requires:
-
**Gravcore technology** acquired through quests or ruins
-
A **signal jammer** to disable defenses
-
A **gravship or shuttle** for orbital insertion
What to Expect Inside
Prepare for intense combat against:
-
Mechanoid strongholds with blast doors
-
High-caliber turrets capable of obliterating pawns
-
New foes like the **Cyclops mechanoid** (armed with a gatling beam repeater)
-
Mech vats spawning reinforcements
Destroying **cerebrex stabilizers** weakens the core’s shield but activates more defenses.
The Final Choice
Reaching the **cerebrex core** gives two options:
- Destroy it to stop all mechanoid activity planetwide
- Harvest its power for advanced technology while raids persist
Both choices let you continue playing post-mission, shaping your world permanently.
Why the Mechhive Matters
- **First ending that removes a core threat without ending the game**
- Destroys mechanoid raids, enabling safer expansion or ArchoNexus ending pursuits
- Serves as a quasi-New Game+ when combined with ArchoNexus restarts
- **Trade-off**: Eliminating mechs removes their resource drops but grants long-term safety
Community Reactions
- Praised for its dynamic, game-altering consequences compared to traditional “escape ship” endings
- Comparisons drawn to the Anomaly ending’s power-acquisition theme
- Requests for similar faction-specific endings for infestations or the Empire faction
