Phase Crystal is a special mission in Bloons Monkey City.


  • The batch of crystals in the middle of the track has an ability similar to the Bloon Annihilation ability of the Technological Terror, but it has a much bigger range and only takes 12 seconds to cool down.
  • Pass 26 rounds of bloons that move twice as fast as they normally move.


  • This is arguably the hardest special mission in the game because it has 4 paths and the bloons move twice as fast here. Thankfully, the batch of the crystals in the middle has its own version of the Bloon Annihilation ability.
