TD3D

In a 3D environment, in addition to stopping the enemy from advancing, you may also have to stop the enemy from rising or falling!
You can use towers to block the enemy, but after the enemy gradually becomes stronger, it is better to build the tower on the roadside or wall.
Whether you choose to use low-level but massive towers to destroy the enemy, or use high-level and powerful towers to destroy the enemy, as long as you can stop the enemy, it is an excellent tactic!
In addition to powerful monsters, you also have to pay attention to small and fast-moving critters, but as long as you use towers that attack with a wide range, you don't have to worry!
If you are still not satisfied, use the talent tree to strengthen your tower to an incredible level and make those guys despair!
Next time, you have to be careful of them, they are attacking from all directions...

Game features:
1. The enemy is born at the green ball and goes to the end at the red ball.2. Routes are randomly generated.3. Achieving achievement levels can increase the flow level of waves and challenge and defend more enemies.4. There are multiple series of towers. Each series has three directions for advancement. After advancement, each series has three directions for strengthening. After advancement, there may be different abilities.5. The talent points for strengthening the tower are calculated based on the highest number of kills in a single defense (not limited to levels).6. In addition to strengthening the tower's attack power, talents may also strengthen the tower's special abilities, and can also cause the tower's attacks to trigger debuff effects.7. Enemies may be large or small. Because the radius is calculated, the tower may only detect large enemies at the edge of the detection range.8. Enemies may be fast or slow, and non-pursuing bullets may hit enemies immediately behind the original target.9. The enemy may walk on the wall, and you can also build the tower on the wall, but be aware that ordinary bullets cannot penetrate the wall.
