Crystal Zombie

Crystals are pink coloured zombies that have extremely high health and insanely high damage. They also give tons of exp and cash. They rarely spawn in wave 1-40, spawning more frequently in wave 40+, but they can be seen like a Void Slime in Hard Mode. The Crystal Tank is the hardest normal wave (not boss wave) in the game so far.

Player(s) need to kill 2 Crystal zombies to complete the Mining for Money mission.
