Our guidance
How do I progress my heroes when I am not actively playing the game?
You can utilize the Idle Growth mechanic to continue leveling up your heroes around the clock. Simply go AFK to allow your insect squad to gain experience and grow without requiring your constant manual input during gameplay sessions.
What is the benefit of catching insects in the grasslands?
Roaming the grasslands to catch rare insects allows you to fill your private museum and complete collections. Each insect you successfully collect provides your heroes with unique stat boosts, which can help strengthen your squad for future battles.
Can I change my hero development choices if I decide on a different strategy?
Yes, you can evolve your bug heroes freely and utilize unlimited resets. This allows you to experiment with different builds and tactics for your squad without being permanently locked into your initial development choices for your insect heroes.
