Upgrading your Alliance HQ increases the bonuses you are able to receive from Alliance Tech and increases the Dominance of your Alliance.
Each upgrade Level:
- Grants you additional Dominance Points
- Increases your Dominance Bonus
- Increases the bonuses you are able to receive from your Alliance Tech
Your Alliance needs to fulfill several requirements to upgrade its Alliance HQ:
1. Hold enough Construction Packs. You can earn Construction Packs by participating in Tournaments, or by getting them from the "Info" tab of your Alliance HQ
2. Hold the required number of Black Sites of the required Level
3. Hold the required position in the Alliance Rankings
4. Downgrade an HQ of the required Level or higher. This requirement must be completed only ONCE for each upgrade Level
To downgrade a rival HQ, your Alliance must perform a successful attack on it.
Please note that Alliance HQs cannot be downgraded more than ONCE per day.
If another Alliance successfully attacks your HQ while an upgrade is not in progress, your HQ will be downgraded by one Level, and 50% of the Construction Packs spent on the Upgrade to the lost Level will be returned to your Alliance. If another Alliance manages to perform a successful attack on your HQ while it is being upgraded, the Upgrade will fail, and your HQ will be downgraded by one Level. Your Alliance will be reimbursed 75% of the Construction Packs spent on the attempted upgrade, as well as a further 50% of the Construction Packs spent on the upgrade to the lost Level. If an Alliance HQ is downgraded while an Alliance Tech is being upgraded, the upgrade will continue as normal, and will not be interrupted.
MILESTONE LEVELS
The Milestone Level is key in maintaining the strength of your Alliance HQ. Once an Alliance HQ has been upgraded up to or beyond a Milestone Level, it cannot be downgraded below it.
