CSO hidden

Fun Mode: Hidden is the first part of Fun Mode in Counter-Strike Online.


Counter-Terrorist and Terrorist must cooperate to face a new enemy called the Joker. This mode is only playable in its exclusive map, Harlem with a maximum of 10 players in a match.


In a round, a player will be randomly chosen as the Joker. The Joker is fully-invisible when stationary while half-invisible when moving. He is only armed with a staff. In addition, he has high moving speed and jump, 300 health points and 100 armor points. He is also a little taller than the Counter-Terrorist and Terrorist player models.

For humans, the humans must annihilate the Joker. The player that succeeded to kill the Joker will become the next Joker.
