The event runs for a limited time but can be completed early, if the player collects the final event reward.
By using generators that require energy, the player receives not only items but a special event resource. Energy Booster also increases the level of this special resource.
Collecting the event resource from the field will fill the progress bar on the event icon. Once the bar is full, the player receives a reward. Further collection of the resource unlocks the reward for the next event level.
When the event ends, any unclaimed rewards will be automatically added to the player's profile.
