If you are part of an Alliance, you can participate in an Alliance Event.
Alliances from every Front are competing against each other.
All players Commander’s points add up to reach three different milestones, which reward all the members with crates. In order to receive prizes, you need to score at least one point in the Event.
You can claim the prizes from the Alliance Menu > Gifts. Once you open the Gift, the item will go in your Inventory.
At the end of the Event, Top 10 Alliances across all Fronts will receive an extra prize.
At the bottom of the Alliance Event menu you can check the top 3 member participation.
