DO NOT SPEND MONEY IN THIS GAME. It is a play to win game. I played for over 2 years and spent real money only to find that I still was not competitive in the game. After a recent update in the game, I was unable to access my base. Last Selter asked me to provide receipts for payments going back 2 years before I could get my base back. I only have receipts for up to 1 year as I changed my phone from iPhone to Android. They want payment receipts from both. 2 years of game play wasted and lost.
