Antimatter Power Guide: Endgame Energy Strategy

Before committing to antimatter, make sure you actually need it. Here is how the tiers compare:

When to Upgrade

• Solar → Small Reactor: When you have more than 10 buildings
• Small Reactor → Fusion: When you hit Station Level 7 and power demand exceeds 200/sec
• Fusion → Antimatter: When total power demand exceeds 600/sec (usually Level 10+)

Do not jump to antimatter early. The production chain is expensive and the radiation shielding adds building overhead. Only upgrade when fusion genuinely cannot keep up.

This is the longest production chain in the game. Buckle up.

Antimatter power production chain from uranium ore through refining and neutron initiator processing to the reactor

Step-by-Step

1. Uranium Mining

Uranium ore is found in the outer sectors — usually the Junk Yard near Cerberus or deep asteroid fields. It is rare and often in hostile territory.

Minimum setup: 2 Uranium Miners + Freighter Dock for transport.

2. Refinery Processing

Uranium Ore goes through a Refinery to produce Uranium Fuel Rods. This is a slow process — one Refinery takes 10 seconds per Fuel Rod.

Minimum setup: 2 Refineries running parallel to keep up with one Antimatter Reactor.

3. Neutron Initiator Crafting

Uranium Fuel Rods are processed into Neutron Initiators in an Advanced Assembler. Each Neutron Initiator requires:

Minimum setup: 1 Advanced Assembler with a steady supply of all three inputs. See our Superalloy Guide for Superalloy production.

4. Antimatter Reactor

Feed Neutron Initiators into the Antimatter Reactor. One Initiator produces ~60 seconds of full power output.

5. Radiation Shielding (Critical)

The Antimatter Reactor emits radiation in a radius around it. Any building within that radius takes gradual damage. Radiation Shielding blocks this damage.

Shielding Requirements

Where to Place Shielding

Build Shield Panels in a ring around the reactor, covering all adjacent buildings. The panels do not need to form a complete wall — they create a radiation dampening field that covers a radius around each panel.

Optimal layout:

Radiation shield placement around antimatter reactor - required before startup

Eight panels in a ring around the reactor. Add more on the sides facing your production buildings.

Lead Supply

Lead comes from refining certain ore types (check your Refinery recipes). It is not rare but is not something you probably have stockpiled. Set up a dedicated Lead production line before building your first Shield Panels.

The Hybrid Grid (Recommended)

Station power source strategy balancing fusion baseline, antimatter peak, and solar emergency backup

This gives you:

• Stable baseline from fusion (well-understood, easy to fuel)
• High output from antimatter for heavy-demand buildings
• Solar backup to restart the grid if everything else fails

Power Demand by Station Level

Fuel Consumption

One Antimatter Reactor Mk1 running at full capacity consumes:

• 1 Neutron Initiator per 60 seconds
• Which requires 1 Uranium Fuel Rod + 2 Electronics + 1 Superalloy per 60 seconds
• Which requires ~10 Uranium Ore per 60 seconds (from 2 dedicated miners)

Scale your mining accordingly. Running 2 Antimatter Reactors means doubling all of the above.

The Blackout Recovery Plan

If your Antimatter Reactor runs out of fuel, you lose 500+ power/sec instantly. This can cascade into a full station blackout if your fusion grid cannot absorb the sudden demand shift.

Recovery steps:

1. Emergency solar kicks in (if you have solar panels)
2. Shed non-essential buildings (disconnect Defense, Superalloy Forge)
3. Route remaining power to Uranium processing
4. Restart Neutron Initiator production
5. Feed the Antimatter Reactor
6. Reconnect shed buildings

Reactor Built but No Power Output

Cause: No Neutron Initiators in the fuel input.

Fix: Check the entire chain — Uranium Miner → Refinery → Advanced Assembler → Reactor. Any break in the chain means no fuel.

Buildings Near Reactor Taking Damage

Cause: Missing or insufficient Radiation Shielding.

Fix: Build Shield Panels in a ring around the reactor. Check the coverage indicator in the reactor’s UI.

Uranium Supply Too Slow

Cause: Uranium miners in a hostile sector getting raided, or not enough miners.

Fix: Add defense to the Uranium outpost. Or find a second Uranium source and set up another mining route.

Chain Keeps Breaking Because of Superalloy Shortage

Cause: Neutron Initiators need Superalloy. If your Superalloy production is already stretched thin by defense and ship building, adding antimatter fuel demand breaks it.

Fix: Expand Superalloy production BEFORE building the Antimatter Reactor. See our Superalloy Guide for scaling strategies.

Frequent Blackouts After Adding Antimatter

Cause: You replaced fusion reactors with antimatter instead of supplementing them. If the antimatter reactor fails, you have no backup.

Fix: Keep at least 2 Fusion Reactors online alongside the Antimatter Reactor. Never go all-in on one power source.
