As one of its daily deals, Amazon Appstore for Android offers downloads of Duke Nukem 3D: Full Edition for Android
. That's $1 off and the best price we could find for this full version of this first-person shooter game. (For further comparison, we saw the first episode for the same price last winter). Deal ends today.
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.)
