Defenses are stationary structures built on your planets to help defend against enemy ships. They are usually considerably cheaper than ships for the same amount of power, but cannot be used in attacks or to defend planets other than the one they are built on.

In combat, all of the defender's defenses will fight just as ships do against an attacker. Unlike ships, however, at the end of the battle each defense has a 70% chance of being rebuilt instantly for free. Note that the chance to be rebuilt applies on an individual unit level, so the 70% rebuild rate is only an expected value, not a guarantee (or limitation).



Just like ships, defenses may require certain technologies and shipyard levels. They are built at the shipyard and take time to build, depending on their cost. They follow the same formula as ships, which is

Time(hours) =
Ore Cost + Crystal Cost
2500 * (1+Shipyard Level)

To add a unit to the queue, click the "add to build queue" button after entering the amount of each unit you wish to build in the field above the button (the default is 1). Once you put a build order into the queue it cannot be removed. You can, however, rearrange the order in which your defenses and ships are built by clicking an item and dragging it to the desired spot. You cannot move the item currently being built.

Unlike buildings, defenses do not take up planetary fields, so any planet can have unlimited defenses. Also unlike ships, defenses destroyed in combat do not get added to the debris field.

Defense Descriptions

Missile battery.png Missile Battery: The most primitive weapon in the universe, the Missile Battery uses cheap combustion-powered explosives to deter light enemy invaders.
Laser cannon.png Laser Cannon: Slight upgrade to the Missile Battery. The Laser Cannon uses high-powered focused beams of light to defend your base.
Pulse cannon.png Pulse Cannon: The Laser Cannon's bigger brother, the Pulse Cannon packs considerably more punch and can withstand enemy attacks better.
Particle cannon.png Particle Cannon: The Particle Cannon has a massive Shield Rating and can withstand hits from most ships, making it an attractive defense against many strong enemy invaders.
Gauss cannon.png Gauss Cannon: The Gauss Cannon uses a magnetic field to hurl high-density metal slugs at enemy invaders. Significantly more firepower than its predecessors, and astonishing Hull Rating.
Plasma cannon.png Plasma Cannon: The most powerful defense ever created. Utilizes Plasma Technology to create a giant wave of plasma that has the ability to neutralize even the mighty Athena Battleship in one shot.
Anti-ballistic missile.png Anti-Ballistic Missile: The only way to defend against a strike by an opponent's Interplanetary Ballistic Missiles. These are an automatic base defense.
Decoy.png Decoy: The decoy is a defensive structure designed to absorb large hits. While it has no offense, its high shields and the fact that nothing Rapid Fires against it makes the decoy able to withstand large amounts of fire, making it a great addition to a defensive position. You may only have one of each decoy at a time.
Large decoy.png Large Decoy: The Large Decoy functions the same as the regular Decoy, but has even higher shield and hull. Like the regular Decoy, you can only have one.
