Not actually that , but i have came across some easter eggs / Hidden Stuff in this update.
How about this! tacticsoft will hide across the game 15-10 easter eggs , with each egg having their reward !
Say You found … Egg Nr.9 , reward 50 tokens.
If you found all eggs , you get 5-4 premium packs / boxes.
I mean yes it will be quite har to pull off since it MOST LIKELY be a point and click , like you found it , click it and it adds. The development of it might take a while.
As to hiding them around the game :
You could find one in your inventory , one in the settins etc.
