Counter Strike Online Wiki

Room restrict limitknife.pngHammer is an exclusive melee weapon in Counter-Strike Online.


Empty slot.png This weapon has Part System installed.

Although it is slow and inefficient as a weapon, the secondary attack from it can knock back incoming zombies far away. It is only usable in Zombie: The Mutation, Zombie: The Hero and Zombie: The Union.

Hammer can be used in Zombie Scenario after the player purchases Melee Weapons License.

After the Free Update patch, this weapon becomes a free default weapon in all player's inventories.

  • Before the Free Update patch, Hammer and Nata Knife were sold with game points in South Korea region and Counter-Strike Nexon: Zombies, and cash points for other regions.
  • The hammer is the only melee that deals more damage with its primary attack.
  • Hammer also appeared in Zombie Shelter (original mode) as an upgraded collection melee weapon.
  • This is the first melee weapon that can change mode. The second is Beam Sword.
  • This is the first melee weapon that has speed reduction before Ruyi Stick.
  • In CSN:S, Hammer along with SKULL-9 and Nata Knife, is caregorized as an item rather than as a weapon, causing it to break in CSN:S May 20 2021 update. The bug got fixed in September 15, 2021 Update.
    • Parts can't be attached to the weapon. (Will faill in the process, but parts won't be lost)
