Defense

Defense installations are built in the Weapons factory, just like ships. They stay on the planet, automatically join every battle there and need neither fuel nor escape flights. The table below compares all installations.

Why build defenses?

• It deters attackers: raiders prefer targets with weaker defenses.
• After a battle, a large part of the destroyed installations is repaired automatically – lost ships, on the other hand, are gone.
• It protects your planet even while your fleet is away.

Guns and shield domes

Guns range from the cheap Mortar to the mighty Solar cannon. Shield domes do not attack, but they bring a huge shield and lots of hull into battle. You can build each of the two domes only once per planet. If one is destroyed, you may build it again.

Research that strengthens your defense

Weapons technology, Shield technology and Defense systems work on defenses just like on ships: +10% attack, shield or hull per level. You need Energy technology, Targeting systems, Particle analyzer and Graviton technology mainly as requirements for the stronger guns. The Synth network and the Miner specialization (stronger dome shields, cheaper defenses) add a little extra on top.

The particle cannon threat

With the Particle cannon, an opponent can destroy your defenses from a distance without sending a single ship. The Particle shield protects you: it absorbs the fire as long as its accumulator lasts. Read more under Particle attack.
