Empire of Cats is the first saga in the game and is unlocked from the beginning. This mode contains 3 chapters, with 48 levels in each. Collecting all Treasures available in each stage is the main goal in this mode.
Chapter 1: The Battle Cats Rising
Units cost 33.3% less than they normally would in this chapter (example: Macho Cat costs 50¢ instead of 75¢).
All enemies in this chapter have a strength magnification of 100%.
These Treasures can be split into three groups (in ascending order): Inferior, Normal, and Superior. When completing a stage, you have a chance to earn a Treasure (quality is random). You can try a stage again to get higher Treasure quality.
Using a Treasure Radar in a stage will result in a guaranteed Superior Treasure.
Completing a set of Treasures activates its associated effect. Effectiveness is determined by the quality of the whole set.
