Alliance invasions

An alliance admin declares the war and sets how long it lasts (1 or 3 months), how victory is measured (destroy enemy ships, steal resources or both) and how hard the target is. Targets are shown in spice and calculated from the opponent: from the spice value of their ships or from their estimated production.

How it works

1. After the declaration a fixed peace period of 7 days applies. Battles do not count yet, and the defenders can prepare.
2. Then the war runs. Both sides have the same victory condition, each measured against the other side. The invasion page shows your task and the progress of both sides.
3. During the invasion you attack each other. The usual limit on repeated attacks against the same player does not apply between the two alliances. Attack zones still apply.
4. Whoever reaches their target first wins at once: +50 % resource production for all members, depending on difficulty, victory condition and duration for a few days up to several weeks. If nobody reaches their target, the defenders get 7 days of +50 %.

Coalitions: the attackers can invite an alliance or wing partner, who has to agree. Only then may the defenders also bring in a partner during the peace period, whose alliance already existed before the declaration; the attackers target is then recalculated. An alliance can never be friend and enemy of the same alliance at once. After a war the sides stay in a post-war state for a few days.
