Eclipse: Second Dawn for the Galaxy
Eclipse: Second Dawn for the Galaxy explained: exploration, influence, technology, ship upgrades, economy, combat and eight-round scoring.
Lead a human or alien civilization through eight rounds of exploration, expansion, technological development and fleet construction.
Every action increases your civilization’s upkeep pressure, so expanding farther and building more assets must be supported by a functioning economy.
Why We Love It
Eclipse makes military power an engineering problem. A fleet is not just a number of ships: technology and ship-part choices determine speed, initiative, accuracy, defenses and damage.

Rules overview
During each round, take actions such as Explore, Influence, Research, Upgrade, Build and Move, paying the associated influence cost through your economy. Conflicts resolve after actions, then the upkeep phase determines whether your civilization can sustain its expansion. The game ends after round eight and scores controlled sectors, reputation, technology and other sources.
Key decisions
Editorial analysis: Expansion is only valuable if you can afford the influence and population it requires. Before researching or upgrading, identify which ship class will actually use the technology. Military deterrence can sometimes produce more value than a battle, especially when combat would expose an underfunded economy.
Common questions

The Second Dawn base game lasts eight rounds.
Can ships be customized?

Does controlling more space always help?
