▼Worldview Natural disasters of unknown cause occur frequently in various parts of the world, and an unidentified mineral that begins to appear immediately afterward - ``Originium''. With the development of technology, when the energy contained in the source stone (Originium) began to be utilized in industry, civilization made rapid progress. However, at the same time, people called "infected people" began to appear around the world.
While infected people possess great power, they are also seen as terrifying beings who can spread infection, and people hate and persecute them. Some of the infected people who had been treated unfavorably did not like it and rose up in rebellion, vowing to bring a new order to this world.
Amid such confusion, a medical institution called ``Rhodes Island'' was established to solve all the problems caused by infected people. When you, the brain of Rhodes Island, wake up, the world begins to change dramatically.

Love the characters and the lore. The tower difference style game play is very fun. With thick lore and absolutely stunning characters to offer. Every stage will differ depending on the new enemies to come, your operators to bring and every decision you make. Of course there's stronger charters but the community will definitely show you wrong if you think you can't win with only 3 stars.

Well balanced game with fascinating characters. Not pay to win, but think (or google) to win. It's not too hard to win without high rarelity characters. I pay only monthly package, but it's enough to go thru the whole latest chapter within few days after it has been introduced.
