I’m glad to announce that the new monthly update for Deisim is now live!

This update introduces a new disaster: “The Alien Invasion.”

When this disaster happen an alien capsule crashes into one of your cities, finally letting you encounter the aliens.

To celebrate Christmas, you can also add a new limited tile: “The Christmas Forest.” This miracle is available only during the event, so be sure to place it in your world while the Christmas magic lasts! Of course, the tile is saved like the rest of your world, so once placed, you can keep your little North Pole forever.

I can’t wait to show you more about the next monthly update, and I hope you enjoy this one!And if you really like aliens you may be interested about this small teaser for the next update ;)

Cheers,

Myron
