As one of its daily deals, Amazon Appstore for Android offers downloads of Fields of Glory for Android for free. (Google Play offers it for the same price, but it doesn't include the MP3 credit mentioned below.) That's $1 off and the best price we could find for this arcade-style tank game. Deal ends December 7 at 2 am ET.

If you haven't claimed it yet, you can receive a $1 Amazon MP3 Credit for free with this download. (It can only be claimed once per Amazon account until December 31.)
