When the event starts, all the alliances must first register.
There are 16 fortresses in total, 12 Bunkers and 4 Facilities. For each Fortress your alliance take control over, your alliance will get different rewards.
Your alliance Leader and R4 members can choose which Fortresses they want to challenge for during the registration stage.
If your Alliance took control of a Fortress in the previous event, your Alliance will automatically register in the contest of the same Fortress in the following event.
During registration, Alliances can choose 3 time slots (from 5) to challenge for the Fortress.
Alliances that have auto-registered can register to challenge 2 other Fortresses.
The alliances get 2-hour to challenge, an Alliance can take Control of the Fortress by occupying the Fortress for 30 minutes continuously.
If the fight continues and no alliance can hold continuously for 30 minutes, the alliance that holds it last at min takes final control
When attacking the Fortified building it acts as a settlement, troops don't die (Troops only get wounded but won’t die as long as the hospital capacity is enough).
You can teleport your Settlement to the Fortress grounds. By porting you eliminate travel time, It will save you time and increase the success rate of your alliance wining the fight.
Its is Important to join rallies set by your strongest members with a higher battle power (BP).
