Absolute Zero is the final upgrade of path 2 for the Ice Tower in both BTD5 and BTD6. When used, it will freeze the entire screen of bloons for 4 seconds (including White Bloons and Zebra Bloons). In the mobile versions of Bloons, it also slows M.O.A.B. Class Bloons down to half speed (this can stack with Sabotage Supply Lines). Absolute Zero can affect White Bloons, Zebra Bloons, and Camo Bloons without the specialty building or X/3 Monkey Village. It takes approximately 15 seconds to recharge this ability on Fast Forward with no support.

In BTD6, this upgrade makes a return, but it is now a Tier-5 upgrade with a much more powerful ability. In addition, Ice Shards is no longer possible to purchase in combination with this upgrade, along with the fact that Arctic Wind is instead the upgrade that leads towards this upgrade. The Absolute Zero upgrade also has a less powerful upgrade counterpart Snowstorm.  Its primary difference is that this upgrade can now freeze M.O.A.B-Class Bloons instead of simply slowing them down. It has a short freeze duration of only 3 (?) seconds though, at the current moment. It costs $TBA on Easy, $TBA on Medium, $TBA on Hard, and $TBA on Impoppable.

TipsEdit

BTD5Edit

  • In BTD5 Mobile, it is noteworthy to know that the ability can also slow down MOAB-class bloons, not just normal bloons. Also, there is quite an outstanding difference in power between the Absolute Zero ability when compared to Sabotage Supply Lines.
    • Absolute Zero slows MOAB-class bloons immediately to half speed; Sabotage Supply Lines only slows down any bloons that come out, including those that enter the map or those that derive from children bloons.
    • Absolute Zero also freezes the non-MOAB-class bloons on screen, so it can be in favor or out of favor to your defenses, depending on whether the defense can handle frozen bloons well or not.

BTD6Edit

Differences Between BTD5 Flash and BTD5 MobileEdit

Buff Absolute Zero ability now slows M.O.A.B. Class Bloons to half speed.

Update History (Bloons TD Battles Mobile)Edit

4.6

Nerf Absolute Zero price increased ($2000 → $3500).

TriviaEdit

BTD5Edit

  • Absolute Zero in action
  • Absolute Zero icon
  • Button to activate Absolute Zero
  • BTD5 artwork
  • Legendary Ice Tower Card with Absolute Zero upgrade
  • This is the only upgrade for the Ice Tower that does not have an animated element to its appearance on the track.
  • Although some claim that this ability is useless, it can slow MOAB class bloons in the mobile version, making it an exceptionally economical alternative to 4/x Sniper Monkeys or even the x/4 Ninja. Furthermore, Ice Shards have unlimited popping power and can decimate normal grouped bloons. When packed together with normal bloons, Ice Shards can even shred through M.O.A.B. Class Bloons.
  • Absolute Zero is the cheapest of the Special Abilities in Bloons TD 5, by the cost of the final upgrade alone. In Bloons TD Battles Mobile however, Glue Striker is the cheapest.
    • If the cost of all the path 2 upgrades are counted, the Tack Shooter's ability Blade Maelstrom is cheaper with a total cost of $3705 compared to $4450 for the Ice Tower.
  • Absolute Zero, in real life, is the equivalent of 0 K, which means -459.67 °F or -273.15 °C. At this temperature, elementary particles are in a state of complete stasis. Attaining absolute zero is impossible since it would violate the 3rd law of thermodynamics and quantum mechanics. The position-momentum uncertainty principle in quantum mechanics states that the standard deviation in position times the standard deviation in momentum equals the reduced planks constant over 2. A particle at absolute zero would have 0 momentum and a standard deviation of momentum equal to 0. A standard deviation of position multiplied by 0 (the standard deviation of the momentum of a particle at absolute zero) equals zero and not Planck's reduced constant over 2, thereby violating the position-momentum uncertainty principle. Therefore, absolute zero is impossible to attain. Yet another reason quantum mechanics challenges every law of science. (Such as, on an atomic level, an atom can be in two places at once or not exist at all)
    • With this information, it is illogical to have some moving frosty air during freezing.
    • Also with this information, the Zero Point Energy Machine description mentioning "pure coldness" is not possible in real life.
    • It also is illogical that the MOAB-class remain unaffected by extreme coldness, even though all other bloons froze. However, in the mobile versions of BTD, this ability will slow MOAB-class but the Glue Striker ability will not.
  • This ability can backfire if you do not have any towers that can pop frozen bloons, so you will need towers that can pop frozen bloons, such good towers would be Bomb Shooters and Juggernauts .

BTD6Edit

BTD6 Absolute Zero

BTD6 artwork

  • The previous upgrade, Snowstorm, is a weaker variation of the BTD5 Absolute Zero, being unable to freeze White and Zebra Bloons, however this upgrade is better being able to freeze everything excluding the B.A.D., including M.O.A.B-Class Bloons.
