Basement Culvert (zs_culvert) (Groundwater in Counter-Strike Nexon: Zombies) is the second Zombie Scenario: Season 2 map in Counter-Strike Online. It is a survival-based map.

Background

Time after chasing the wounded Dione

Hello. This is Senior Researcher Soy from Aegis Institute. Unfortunately, we've missed a chance to capture Dione. However, it has been badly injured by us. I've received an order from the headquarters to continue the pursuit. We are requested to capture it alive but if that is impossible, we can kill him. Let's do our best, everyone!

LS team found Dione hidden inside the culvert after their continuous pursuit and have tired to capture him. However, Dione noticed it and went hiding into the darkness. At the same time, countless zombies are coming from everywhere to welcome the LS team.

Overview

Culvert takes place in a big sewage treatment plant.The players need to face the zombies coming from the sewers. In later rounds, Dione will start attacking players by rolling from the dark corners, spewing poisons from the ward above the sewers, and using its tentacles to make the game harder.

There are a total of 15 rounds with 3 minutes time limit for each round.

Trivia

  • Culvert is a sewer or drain crossing under a road or embankment.
  • Phoenix in classical mythology is a unique bird that lived for five or six centuries in the Arabian desert, after this time burning itself on a funeral pyre and rising from the ashes with renewed youth to live through another cycle. It is also referred as Ababil in classic Arab literature.
  • In this map, Dione had evolved into Siege Type Dione and later escaped to finally evolve into Angra in the next chapter.
  • During initial release, blood splatter will comes out if you attack the center of the map with certain melee weapons. This easter egg also can be performed in Trap, Another Truth (boss arena) and Last Ride (boss arena).
  • After Zombie Scenario Re:boot, you will meet 2 or 3 Siege Type Diones. Moreover sometimes when both of them are rolling one might get stuck in the dummy animation, but will disappear after some time.
  • There was a bug where the HP bar for the regular Dione may randomly appear and disappear. Despite Dione is being shot at, the HP bar does not deplete at all unless Bendita is used.
    • Using Bendita to attack Dione when it's attacking from the top floor will immediately end the round as soon as Dione leaves its attacking position. This is best used during the later half of the rounds, as demonstrated here (fixed in later update).
  • After the 26 March 2015 update, this is the only map in Zombie Scenario which keep its bonus round, and the only map in Zombie Scenario where the Pierrots makes appearance.
