Phase Crystal

The Phase Crystal is a Special tile in Bloons Monkey City. Players must defend against 26 rounds of double-speed Bloons. The crystals in the middle has an ability identical to the Technological Terror's Bloon Annihilation (even the glitch that prevents it from popping camos), except with a cooldown of only 12 seconds.
