Completed – Star Defense (iphone)
A visually impressive but standard tower defense game by premier iphone developer ngmoco.
The variation that this game brings are full 3D stages with the ability to perform Google Earth style spinning and zooming. Other than that the standard game play remains the same where you place towers to prevent the attackers from reaching their destination. Sunk around 6 hours into it to complete the 7 stages on normal. Challenge mode provide additional replay value.
7 different worlds, 3 difficulties, challenge mode and a range of towers & enemies.
