Hello @Bluemoonenergy, welcome to The Ants!
It’s great to see new players joining the game. I understand that getting started can be a challenge, but we’re here to help. To clarify your question about attacks, even with a shield around your anthill, it’s important to note that the shield only protects the main anthill, not the “resource nodes”.
The attack likely occurred at one of the “resource nodes”, and you can check this information through your “Battle Report” message box.
As for building a strong army, focus on evolving your troops and upgrading your anthill with the rewards you’re obtaining. Use these rewards to enhance your constructions and develop your skills. Additionally, explore the different available troops and strategically plan your formation to optimize your performance in battles.
Here, in this post, you’ll find more information on Tips for beginners (different modes of play). And don’t hesitate to ask for help in the global chat; many people will be willing to assist.
I also appreciate @ZeroOne for providing valuable information. Collaboration among ants is truly essential.
Good luck, and may your ants thrive!
