工程站是分佈在太陽城周圍地圖上的高科技建築，為控制它們的聯盟所有成員提供有價值的增益。

這些增益對玩家提昇實力和在活動中提高屬性非常有幫助。

要控制一個工程站，一個聯盟必須將其領地連接到該工程站。這可以透過在工程站旁建造聯盟總部或聯盟旗幟來完成。您不能攻擊不與聯盟領地接壤的設施。

1. An Alliance must occupy a facility for a continuous duration of 30 minutes to gain control.

2. The control of a facility lasts for a period of 3 days. After this time, the control can be rechallenged as follows:
a. The current controlling Alliance (Alliance A) must defend the facility for 24 hours to maintain control.
b. Another Alliance (Alliance B) can take control by occupying the facility for 30 minutes.
c. If Alliance A regains control from Alliance B, they only need to occupy the facility for 30 minutes, as a control switch resets the timer.

Note: If the facility is in a vulnerable condition, the bonuses will not be effective.

3. Rewards are provided to the controlling Alliance the first time a facility becomes available for contention.

Attention: Facility of the same type will stack their benefits but will not if they have the same level.

For simplification:
1.) Same type, different level = benefits WILL stack.
2.) Same type, same level = benefits WILL NOT stack.

An alliance can benefit from a total of 12 Facilities. This is of course, difficult to achieve. Still, it is possible through strategic banner placing.
