This is a fun game but be prepared to spend thousands. The developer IGG allows bots. And dose nothing to regulate them. It is a cash cow for them to allow them. The bots do several thing one inpaticular is dropped sheild you will be hit with in minutes and troops are very expensive. The 2m. Each you need will be around 5k. So be careful when spending you will lose it all and igg don't care. And will do nothing when you report it.
