- Triangles are pretty common mobs that generate all around the map.
- They can be destroyed by 5 shots from a regular tank without any upgrades, or 3 shots from a regular tank with "Bullet Damage" upgraded 3 times.
- When killed, they give out 25 points of score to the player who killed one.
- They might be confused with the drones (bullets) of the Overseer, Overlord, Manager, Hybrid and Overtrapper; these bullets are smaller, darker in color, and move.
- They don't spawn in the Pentagon nest.
