A very, very large bomb. Someone put a stop to craziness!
~ BTD6

Tsar Bomba is the final upgrade of Path 2 for the Monkey Ace in BTD6. It creates a much more damaging explosion that does 3000 damage that also stuns all Bloons excluding the B.A.D. (which can't be stunned at all) for 8 (?) seconds. Cooldown for the Tsar Bomba is 45 seconds upon activation. It costs $29,750 on Easy, $35,000 on Medium, $37,800 on Hard and $42,000 on Impoppable.


  • This upgrade is useful against fully destroying everything below ZOMG health (including Fortified DDTs) easily in one ability explosion. In addition, it becomes handy at stunning all the ZOMGs on screen.
  • The massive damage that the Tsar Bomba nuke deals makes this upgrade very useful for beating Rounds 94, 96, 98, and 99.

  • The upgrade's name is a reference to the Soviet Union nuclear bomb Tsar Bomba, the most powerful explosive weapon ever detonated.
  • The Tsar Bomba ability icon is the same icon as the artwork of the upgrade. The Ground Zero ability icon is a green bomb shell despite its artwork depicting the plane dropping the bomb.
  • The plane for the Tsar Bomba most likely appears to be the Tupolev Tu-95.
  • This BBC news coverage about the Tsar Bomba explosion has more information about the plane that dropped the real-life Tsar Bomba.
