Alliance base

Every alliance has a base. Its members fill one shared treasury with metal, crystal and deuterium, members with the right to manage the base turn the treasury into buildings, and every building gives each member a small permanent bonus.

Donating

You donate from the planet or moon you are on, at least 1.000 resources in all. The donation leaves the planet and reaches the treasury at once. Nobody can take resources out of the treasury again: it pays only for buildings and operations, and a donation stays with the alliance when you leave. Donating is closed while your account is in vacation mode.

Every donation earns you contribution points: for every 1.000 resources, 1 for metal, 2 for crystal and 3 for deuterium, rounded down. The points are yours, not the alliance's. The Base page ranks the alliance's donors of all time and of this week.

Buildings

Each level costs more than the last by the building's cost growth, and every price is multiplied by the universe's resource multiplier; the table shows the first level in this universe. A construction runs in real time, the same in every universe. No building can be raised above the level of the Command Center, which goes first.

The alliance builds one thing at a time. Starting a level pays its whole cost from the treasury, and cancelling it pays the whole cost back. When a level is finished every member gets a message. The sum of all building levels is the base's prestige, shown on the alliance page and in the base ranking.

Who builds

Starting or cancelling a construction and starting an operation need the rank right Manage base. The alliance's leader always has it and can give it to any rank. Every member sees the treasury, the queue and the history, and every member can donate.

Members

The Command Center decides how many members the alliance can have: 20, plus 2 for every level. The limit that counts is the smaller of this and the limit the alliance set for itself. An alliance above it keeps every member, but accepts nobody until it is below it again.

The waiting time

The base counts for you only after 1 día in the alliance: its building bonuses, its operations and its shop. Leaving ends all of it at once, and joining again starts the waiting time over.

The building bonuses are Permanent bonuses and add to research, officers and the rest of that bucket (How bonuses combine).

Operations

An operation is a bonus for the whole alliance for a while, bought from the treasury by a member with Manage base. It is paid per member who is past the waiting time, for at least 5 members, so a larger alliance pays more. At most 2 run at once, and each kind can start again only when its cooldown, counted from its start, has passed. An operation cannot be cancelled or refunded.

Operations are Temporary bonuses, like a boost of the same kind (How bonuses combine).

The alliance shop

The shop opens with the first level of the Contribution Exchange, and its higher levels open more tiers. You can buy each item 2 times a week, and once more for every 5 levels of the Exchange. An item whose system this universe does not run cannot be bought.

The tag colours, the glow and the gold tag change how your alliance tag looks in the galaxy view and the player rankings while you are in any alliance. The gold tag replaces any colour.

Leaving and dissolving

When you leave, the bonuses and the operations stop for you at once; your contribution points and your tag stay with you. The leader cannot leave or be kicked: the leadership has to go to another member first, or the alliance is dissolved.

Dissolving the alliance destroys its base for good: every building level, the treasury and a running construction or operation are lost. The members keep their contribution points.
