I hadn't even heard of "Navy Patrol: Coastal Defense" until Joe Bayen, a CEO at ICS Mobile e-mailed me. My initial thought was "oh great another tower defense game, just what the iPhone needs." Dutifully I watched the promo video bellow and ended up being very interested. The game appears to have all the regular Tower Defense gameplay plus some pared down RTS mechanics. The video bellow becomes interesting and new at about the half way point if you want to judge for yourself.
The RTS elements appear to include experince points, skill trees and, some degree of unit targeting. I'll post a followup once the game is released. It looks like this could be the game to reinvigorate what is rapidly becoming a very tired genre on the iPhone.
