Where to build a Stellar Cannon

The game's own requirement line, then the conditions of the first stage (possible) and of the planet or star it goes around (placement_rules).

Must be built on a Neutron Star or Pulsar.

The planet or star
  • Cannot build on planets that have unresearched anomalies discovered by us or any other Empire.
  • Must be built around a Neutron Star or Pulsar.
The system and the empire
  • The system has a starbase
  • Cannot build outside Empire borders.
  • Cannot build due to existing Megastructure.
  • Cannot build in systems that have not been surveyed.

Stellar Cannon stages

Cost lines with a condition apply only to the empires it names (bio-ship empires pay food instead of part of the alloys).

How it's counted

Totals in the head count only the costs every empire pays: 2,000 Alloys, 300 Influence.
