Tips[]

  • Can pop camo by default.
  • Can pop lead with all upgrades tier 3 and beyond.
  • Can damage HTAs with the rail gun and gas for the left upgrades, the rotors for the middle upgrades, 4M, and 5M.
  • 5R ability gives 6000 lives, then 300 frames later (10 seconds at normal speed), removes 5900 lives, leaving you with 1 if you had less than 5901 left.
  • 3R can infinite stall bloons, but sometimes causes a regrow farm.

Advantages/Disadvantages[]

Advantages[]

  • Extremely powerful when upgraded.
  • The helipad can be built anywhere, since the actual damage source follows the mouse.

Disadvantages[]

  • Expensive.
  • Very weak without upgrades.
  • Weak against high tier MOAB-Class bloons.
  • Requires micromanagement.
  • The helicopters have collision, so you can only build so many before they get in each others' way.

Known bugs[]

  • Helicopters can stick into the corners or edges of the map, unable to get out.
  • Selling Relief Aid before temp lives are taken keeps them permanently
