Sledgehammer is a special support weapon in CrossFire, available in Challenge Mode.
Overview[]
The slegdehammer is made of black heavy metal from the handle to the blade, with the red aura on it.
Soldiers can use this weapon to inflict a large amount of damage toward tough enemies or bosses, but it's main usage is to stun boss whenever the prompt appears. If a boss is hit like this, it'll drop down to its knee and be immobilized for five seconds, and soldiers can attack him freely with increased chance to score critical hits.
