Meet the Megagym

July 20, 2026

Mayor, it is time to make room for something truly exciting — a brand-new megabuilding is coming to SuperCity!

Bright, modern, and full of energy, it will become a wonderful addition to your city. Its attractive design will look beautiful in a lively downtown district, a peaceful residential neighborhood, or a special area filled with your favorite buildings.

But the it is more than just a lovely new landmark!

More beauty, more space, more possibilities

Every Mayor knows how precious city land can be. There are always more beautiful buildings to place, new areas to design, and creative ideas to bring to life.

The new megabuilding will help you use your available land more efficiently. It combines the benefits of several buildings while occupying less space. This means you can save valuable land, organize your city more effectively, and still have plenty of room for decors, roads, parks, and future additions.

Whether you enjoy carefully planning every neighborhood or simply want to make your city even more productive, the new megabuilding will be a useful and attractive part of your collection.
