Bloontonium Turret

The Bloontonium Turret is a small machine looking quite similar to the Monkey Engineer's sentries. It fires depleted bloontonium darts which can pop any bloon. It has slow firerate and mediocre range but its upgrades can make it stronger and a force to reckon with. The first path is based on improving the bloontonium effects. The second path gives it the power to fire missiles instead of darts. The missiles can pop black bloons. The third path focuses on improving its speed and eventually giving it three other guns.
