Pretty good variant in the tower/castle defence genre. There's a selection of different units to deploy and they can be upgraded 3 times per level. As stated by the others, you have to pay close attention to how much things cost and choose wisely, otherwise you'll let the bad guys get through.

There's a minor bug in there somewhere because I was awarded several achievements that I know I didn't get - but otherwise the game itself plays well enough.

There are better choices available.

3/5

played this game before elsewhere and as I recall it is not the best castle defence game out there. You get to upgrade 3 times in game and that requires a lot of gold and you have to have enough fighters to kill the enemies before they get to the end of your fighters and head for the last guy at the top, who despite looking like a big and heavy hitter is the weakest of the lot. You get spells along the way in this game and you will be able to replay levels but you get no bonuses for doing so.

this plays ok but once the defenders are in place you can only sit and watch the ensuing battle. when you have enough cash you get the choice of upgrading your defenders or using an available spell, which also requires cash to use. 10 gold per normal enemy and the bigger guys give a bit more but not really enough to make the defence as good as it could be.

2/5
