Defense

Defenses are static units built at each planet. They never leave the surface, but they regenerate cheaply between battles.

Tiers

• Light — Rocket Launcher, Light Laser.
• Medium — Heavy Laser, Gauss Cannon, Ion Cannon.
• Heavy — Plasma Turret.
• Shields — Small Shield Dome and Large Shield Dome (one of each per planet).

Regeneration

After a battle, 70 percent of destroyed defenses are automatically rebuilt for free. Plasma Turrets are the only Heavy-tier defense, so high-level commanders rely on a deep stack of mediums and a few Plasma Turrets to absorb capital ships.

Rapid-fire matrix

Like ships, defense units have rapid-fire interactions against specific attacker classes. Open the Defense screen for the matrix; in particular Light Laser and Rocket Launcher are wiped out fast by Bombers and Cruisers.

When to defense vs fleet

Defense is best when you must go offline. Active commanders should keep most resources in a moving fleet (raid + return) rather than a planet bunker, because defense regenerates damage but never deals it back at scale.
