These are special events that take you through a chain of tasks with a common subject matter, a particular theme, or a holiday in mind. The subject matter of these events can be completely unexpected: You could be asked to tame a volcano, build a large dam, launch an elevator to space, conduct an archaeological excavation, explore a tropical island, guess the secrets of the Pharaohs, find the lost city of Atlantis, or make the desert bloom. Your goal is to complete all the tasks before the event ends. The tasks usually involve building all structures from the event, and completing contracts in special factories. Doing so will earn you a special achievement and unique gifts.

Visit Megapolis, take part in events, build unique buildings, complete all the tasks on time, and get exciting rewards: achievements and unique buildings that you would not be able to purchase at the Store!
