Dart Tower

The Dart Tower is the basic tower. It starts as the only tower you can make in Bloons Tower Defense 4. It throws darts (hence its name) at a fairly average pace. It can upgrade to piercing darts, which allow it to pop 2 Bloons (not layers), Extra Range, Spike-o'-Pult, and Triple Spike-o'-Pult. It costs 170 on Easy and 200 on Medium. This tower is better placed at ends of long paths for its Spike-o'-Pult upgrade.
