- This tower is the most Important part of the mission. If it is destroyed, You lose!!!
- The Missile Strike Ability cannot Completely destroy a Boss Bloon, It can only destroy the Original Layer of the Bloon it hits.
- This tower automatically detects camo when bought.
- You can still use this in normal games, but without the abilities. You do so by Equipping an Upgrade Biochip to a Spectre or Ground Zero, and they will change into the S.I.D.E.W.I.N.D.E.R., with the respective upgrades. The Tower will automatically fire HRP missiles at the bloons with the First Target priority.
