Good towers, lousy story. – Four Days: World Defense Review

You'll learn quick enough that the real game is in tower upgrades. And no, that's not in-game but between games. In the tower store. During loading times some tidbits from an odd storyline reveal themselves, but are unconnected & useless. Max your 'com towers' in game & in store for best results. Four stars.
