4/5. fun except that if you place your towers anywhere besides the front then your level gets destroyed and you lose. So in other words ONLY the front part of the track is useful, the rest might as well not even be there!
the game was fun until some engineers got stuck trying to destroy my barricade (outside the range of my cannons and guns). BUGZ! :( Still 3/5 for effort though.
REALLY fun game, except for the upgrade/cash system. I didn't get my reward after the map completion? Or did I? Its confusing and this is why most games have something like Gold Coins and Gem Stones to make it clear. You could have Dollars to use in mission, and perhaps bullion, gems, credits, etc to use in the store out side of missions.
