Bloons Tower Defence 3 can be found Here!Audio:The sounds are pretty nice and clear, and there's an option to mute the game if balloon popping gets annoying.
Graphics:The graphics in the game are clear and define with a nice shine to them.
Gameplay:The BTD idea has always been one I liked, and the new weapons just make the game a whole lot better then ever.
Originality:Still the only type of game out there along with BTD 1&2.
Difficulty:The difficulty just got a lot more varied since you can now choose either easy, medium, or hard and which map (8 total) to play on.
Overall: 4.5 A totally awesome game!
Tips:I'd recommend buying spike-o-pult when you can and putting it somewhere where it can hit multiple balloons in a strait line. Also be sure to buy a cannon before iron balloons are sent out.
