Zombie scenario

Zombie Scenario is the second game mode introduced by NEXON Corporation for Counter-Strike Online based on a custom game mode for Counter-Strike known as Zombie Riot.


Zombie Scenario pits up to 10 players against increasingly hordes of AI-controlled Zombies. Money cap is doubled in this scenario and the amount obtained varies between types of zombies killed and the difficulty of the map. Extra health, damage and barrier durability can also be bought off the buy menu if the player have obtained a sufficient amount of money. The rounds will keep getting harder with different powerful zombies spawning in.

    Z-Noid patch[]

    After 28 January 2016, there are several update:

    • The addition of 12 difficulties: Easy 1 & 2, Normal, Hard 1-9.
    • Different difficulties give out different Daily ZS Clear Rewards.
      • This reward can only be obtained twice per day; once every 12-hours interval.
      • The player can choose what prize to be claimed. It ranges from common to rare items such as rare zombie tattoos and costumes.
      • The Reward Box can be upgraded. If the player obtains a box at low difficulty level, and does not use it yet, then he/she plays another game (in the same day) and obtains higher-leveled box, the higher-leveled box will replace the lower one.
    • The players can now earn dollars and level up by just shooting at the zombies.
    • If the player uses Round Retry item, all players will respawn immediately, instead of running the round all over again.
      • However, all players just have 1 chance to retry, no matter who use the item. If the players still loose the second chance, the game will end.
    • The respawn time has been set to a limit of 120 seconds, increasing as players level up.
    • Zombies are now labeled with a new set of colors to identify their behaviour, they will be common in the hardest difficulties.
    • Removed items: Dr. A's Trunk, Secret Map, Research Tools, Zombie Sample and Confidential Documents.
    • Fixed some bugs.

    As previously stated, players are able to obtain a Reward Box twice per day upon successfully finishing a Zombie Scenario map. The amount of items, duration, quality, quantity and rarity is based on the box level.

    The following items can be acquired:
