• 4 types of marbles drop from all zombies with a certain probability.
• When learning the old lessons, the gauge fills up one space at a time and is displayed in the color of the marbles acquired.
• The more the same color is acquired, the higher the probability of transforming into the desired monster. (Red: Revenant / Green: Yeti / Blue: Dr. Rex / Yellow: Frozen Wrath)
• If you acquire additional marbles after transformation, you will acquire a buff that lasts for a certain period of time. (1 for every 4 gene beads)
• If it is difficult to play during transformation or if you do not like the selected monster, you can manually cancel the transformation by pressing the T button again.
• If the player dies during the transformation stage, they will return to human form.
• In some classes, if you sit down after transforming into a monster, your lower body may be buried in the ground.
