Once You Learn Jump Kick
(Can't Remember What Level You Learn It But It's Relatively Early [First 20 Levels])
Jump Around And Click The Attack Button In Mid-Air To Jump Kick.
- Holding The Button Down Will Make Chuck Drop-Kick Instead, These Do Not Count.
- You Do Not Need To Kill A Zombie, Just Kicking It To Make It Fall Over - Is Enough.
Kicking The Same Zombie Repeatedly Counts, But They Will Die In 2-3 Kicks.
- Achievement Pops Mid-Kick On Your 100th Jump Kick (That Connects With A Zombie)
Good Luck!
