🎯 Defensive Turret
Automatic cannon. Strong kinetic defense even with no troops home. Weak against energy and ordnance.
Strategic role
Provide standing kinetic defense even without a garrison. Its specialization leaves energy and ordnance attacks better answered by suitable defending troops.
Requirements and progression
To establish this building, you need 🏛️ Main Building level 1; 🛡️ Perimeter Shield level 1; research: Point-Defense Protocols.
For later upgrades, the Main Building must also reach the target level. The level table shows the resource and time investment before bonuses.
Power planning
The building definition has no direct structural or active power upkeep. Check the powered extractors, crafting and recruitment that support its use when planning the wider grid.
