Defense units
Four cannons from the Light Graviton Cannon to the Solar Cannon. They need power and stand within reach of the weapons factory.
You place defense units from the window of the Weapons Factory in the Defense tab. They stand at most 200 fields from the factory and occupy the factory's order while they are built. Build as many as you like, the ground just has to be free.
| Unit | Damage per second | Range | Power | Build time |
|---|---|---|---|---|
| Light Graviton Cannon | 3 | 60 fields | 0.8 MW | 4 hours |
| Heavy Graviton Cannon | 8 | 120 fields | 2 MW | 10 hours |
| Laser Cannon Battery | 20 | 250 fields | 5 MW | 20 hours |
| Solar Cannon | 50 | 350 fields | 12 MW | 40 hours |

Power and smog
Without power no unit fires. Like power plants and factories, cannons make some smog, so the edge of an industrial area is a good spot.
On roofs
Up on the skyscraper level, units only stand on roofs. Build the roof platform on a skyscraper and choose the Platform top. The Light and Heavy Graviton Cannon fit there. The platform can also be extended into a hangar for one ship.
Research
In the Research Lab you research every unit on its own. Each level adds range and 8% more damage.
Damage and repair
Creatures damage units. A destroyed unit stands crooked, smokes and stops firing until you repair it. A full repair costs 20% of the build cost, less for smaller damage.
If a Weapons Factory has mechanics, they repair units within its radius for free whenever the factory has no order. Everything about the beasts is in Creatures.
