Realm Defense?

I have played this tower defense game on mobile. Specifically android. But I am sure it is also for the iphone. And it seems like a good game. And the hero system is definitely good enough to play with for some time. So have you tried this tower defense game?

 

I haven't tried this game, but what are the highlights of it?

 

I haven't played this game either i'll check it out

 

Check this gameplay and I am sure you'd love the game. Here's you can see three heroes and the towers in the tournament.
