Counter Strike Online Wiki
You can't get to me.
— A new Joker spawned

Hidden The Joker, also known as Mr. Hidden in some regions of Counter-Strike Online, is the main antagonist character in Hidden mode.


The Joker hides in a ghost town called Harlem. He has the ability to turn invisible so that humans are unable to spot him. However, the Joker's invisibility is limited. If he does not eliminate a human for a period of time, he gradually becomes visible. The Joker is armed with a staff as his primary weapon which is able to kill a single human in about 2 hits. Also, he has faster running speed and can jump higher than the humans, making him an agile enemy.

After the 4 December 2014 update in South Korea, the Hidden mode is renewed with new rules and items:

  • More than one Joker can appear in game: beside the main Joker, who is half-invisible, another player will be chosen randomly to be the extra Joker, or Betrayer.
    • The Betrayer still appears in human form, making the humans cannot camp together anymore.
  • Jokers have a Hidden Bar to show the time. When the bar runs out, another random player will be chosen.
  • Humans can detect the main Joker when turning on the flashlight.
  • Supply Boxes were added.
