Buildings

Buildings increase your production, speed up your constructions and unlock new possibilities. Many need workers.

Construction queue

Each type of production (buildings, ships, defenses, equipment) has its own independent queue. You can queue up multiple levels or elements — they build one after another. A building's construction time depends on its target level and decreases thanks to the Industrial Complex (and its assigned engineers).

Requirements

Each building has requirements to meet before it can be built or upgraded: level of other buildings, technology level, or both. The 🔒 Requirementspage in the game shows at a glance everything you need to unlock the next level. Planning your construction queue in advance with this tool is essential to avoid wasting time.

⚙️ The population bonus system

Some buildings offer a bonus (construction speed, production boost...) that is only fully active if you assign enough workers to them. If you have fewer than the required quota, the bonus is reduced proportionally.

  • ▶Exponential quota: the number of required workers grows exponentially with each level. A high-level building may require hundreds of thousands of workers to be fully effective.
  • ▶Shared workers: Engineers are shared between the Industrial Complex and the Shipyard. Scientists are shared between the Laboratory and the Orbital Station. You choose the allocation from the ⚕ Productions & bonuses page — it is a permanent trade-off between research speed and construction speed.
  • ▶Economic Center: its +4% production bonus per level on all resources is entirely conditional on assigned Civilians. Without Civilians, the building is useless.
  • ▶Headquarters: assigned Officers speed up defense construction. In addition, the HQ passively boosts the damage and resistance of all your existing defenses at each level.

Construction priorities

Early in the game, level up your 4 mines in parallel to secure your production. Unlock the Barracks as soon as possible to start training Engineers — they are the ones who accelerate all your subsequent progress. The Barracks is your most profitable long-term investment.
