Be aware that this app War Machines continues to have errors and some times double charges for in app purchases. They will refer you to Apple to get a refund but Apple seems to have an unstated new policy that they will not refund errors made by their apps. This developer will not compensate you for their errors. So pay them at your own risk. UPDATE but they will undo sometimes if If you send a ticket to the developers and they reject your request and/or they treat you unfairly make sure you respond to the feedback request. Keep it civil and detailed and accurate, giving the names of the WM staff you had contact with. That is what I did and it took them a month but they made me whole again.
