After the Free Update patch, this item becomes a default item in all player's inventories.
When using this set, the human player can jump higher than normal, as high as a Regular Zombie can. It is important at reaching higher places for camping. Thus, the user can jump over teammates to move quicker.
When infected by zombies, the health power will be 70% of the infecter instead of 50%. For example, if the infecter has 7000HP, so the victim will have 4900HP instead of 3500HP.
After 12 March 2015 update in South Korea.
- Humans: Jump height is increased.
- Zombies: When infected, the zombie's health is 70% or 80% of the infector. In Zombie Hero mode, the zombie's health is not decreased after revival.
- After the 18 December 2014 update of South Korea, the Excellent Genes's effect is tweaked to 70%, instead of 90% for game balance purpose.
