The Copa event is a competition in which you pick a side and earn event points as a reward for completing various in-game tasks. Points you earn, as well as points earned by everyone on the same side, contribute toward team progression. The goal of the event is to earn more points than the opposing side.
At the end of the event, both sides receive rewards, the winning team receiving a higher-value reward compared to the second place prize.
In addition, individual contributors may earn rewards by reaching milestones during the event. To be eligible to claim both individual and team rewards, you must contribute at least one point to your team's progress.
Once the event starts, every player must pick a side or team to join. Bear in mind that you may not switch sides during the event.
