Strategy notes
Citadel System Engineering develops the Shields discipline within Fortress and Combined Arms. Hold valuable systems through shields, layered orbital defense, disciplined ground forces, and coordinated production. Its immediate value is +7% research output. The principal counterpressure is that siege, blockade, espionage, and expansion around fortified systems can make static strength irrelevant.
Player hints
This is late-path research. Treat it as a strategic objective measured in weeks or months, and expect rivals to react to the capability. Favor this technology when its Shields benefits reinforce your current economy, fleets, or frontier. Pause the branch if its expected RP per tick is too diluted or its resource costs would stall higher-priority projects.
