Giant Dome — Xterium defense
Planet defense Shield Dome

Giant Dome

In brief: The big dome is the final step in the development of passive planetary defense. Due to the use of equipment that creates a higher electromagnetic field strength, it protects against long-term attacks by the enemy

The dome does not fire — it is a shield barrier: it absorbs damage and protects the planet. Defense is static — it has no speed or cargo hold. "Weapon points" — one structure's contribution to combat power.

Calculator: defense versus ship

Pick a structure and a ship — we'll show the defense's effectiveness multiplier against that ship.

Requirements

To build this structure, you need to raise the following to the required level:

Shipyardlvl 15
Energylvl 7

Defense is built on the planet (the same place as the fleet). Technologies are leveled up in the Laboratory — section Research.
