"Juggernaut (Achievement)" is one of the achievements and trophies available in Dead Island: Riptide. To unlock this you need to kill 100 zombies with Sam B's charge skill. It will unlock upon the death of the 100th zombie.
Guide[]
- Only the final blow needs to be struck using charge.
- The easiest way to achieve this would be to get the zombie to low health first, then charge into them to finish them off.
- A co-op player could also distract/damage the zombie before you charge to finish them off.
- The damage beforehand can come from any weapon, so long as the zombie is finished off with the charge ability.
