A pretty good RTS / Tower Defense hybrid with a few shortcomings that prevent it from expressing its full potential. The biggest problem I had was the fact that the game doesn't tell you which type of enemies appear during the next battle phase (except for the new ones), so you may end up building structures and turrets you don't really need. Apart from that the gameplay loop is nice and there's a good variety of maps and mission types. Oh, and the soundtrack is amazing. One of David J. Franco's best works for sure.
