Events are monthly missions that will test you to your limit. The objective is to fight and kill as many of the special “Covert Ops” enemies in each event. The enemies are unique to each event and boast abilities that may not have been seen before.

You will need Code Keys to access these missions but the more special Creeps you kill the better rewards you will earn. Each event has a grand reward which can range from huge sums of Gems and boosts to brand new Heroes.
