War

There is no button or command to declare war. Towns can form alliances by clicking a button in the town's menu to set the town as an ally.

Civs wars usually have the following progression:

1. Build outposts with siege machines near the town you want to destroy. These siege machines warm up, and slowly increase their rate of fire. A fully evolved siege machine destroys 960 power per 24 hours.
2. You kill players for -12 power and villagers for -4 power.
3. The enemy uses Catapults, TNT (either placed near the edge of the outpost or shot from cannons) to reduce your outpost's power to zero (so the outpost can be blown up).
4. You try to stop them by killing them or building walls/waterfalls to block the TNT.
5. Once the enemy town reaches zero power it will lose an upgrade (the outer ring crumbles to gravel). If a settlement reaches zero power, then it loses it's TNT protections. Have fun blowing up the town.

Power generation:

Most utility buildings and some defense buildings produce power. Read the description of the building for an exact amount. Towns also generate power every 24 hours.

Housing buildings consume power (NPC and player housing). Don't build too many houses without building utilities or defenses to generate power for them to consume. Building too much housing without building utilities will make your town easier to destroy.

Town Karma / Hardship:

Civs Towns have a score called Karma (or Hardship), its used to balance the attacks and wars between towns.

1. If your Town has negative karma, and gets attacked, the attacker must pay a certain amount of Money (Vault) to the target town to activate their Raid Porters and deal Power Damage.
2. Attacking a town with raid porters or dealing power damage to it, transfers karma from that town to yours.
3. Attacking a town with positive karma, reduces the karma score of the target town but loots money from its bank.
4. Your town karma goes up when attacking and goes down when getting attacked.

Karma is meant to be a town war regulator, punishing big towns for attacking weaker ones that have negative karma but rewarding those who attack warmonger towns that raid others frequently.
