Toxicity (zs_trace) (Poisonous Wound in Counter-Strike Nexon: Zombies) is the first Zombie Scenario 2 map in Counter-Strike Online.

Official Description[]

One year after the Lost City incident. Inside the helicopter flying over Caribbean Sea sky.

"Hello~ brave LS team! I'm Senior Researcher Soy from Aegis Institute, you guys can start entering the operation area. As you know, the power of the zombies has been weakened after the Lost City incident. However, we do not know whether Dr. Rex is developing another batch of zombies or not. Hence, our goal for this, is to find clues on Dr. Rex. I'll provide more information about the operation area. Good luck guys!"

The communication from Aegis laboratory has ended and an order to proceed has been given by the captain of LS team. Team Alpha started to parachute and soon after, an unknown sound can be heard from the jungle.

Story[]

  1. The Aegis Research Institute, hearing rumors that Dr. Rex had conducted research in South America in the past, dispatches Alpha, Bravo, and Charlie teams from LS Units to investigate.
  2. Aegis Research Institute expected that a lot of information could be obtained from this area, as a missing case presumed to have been caused by a guerrilla occurred in this area. However, they were greeted by a large number of zombies.
  3. Zombie corpses here are reported to be living uncontrolled by Dr. Rex.
  4. With the appearance of the prototype Dione, Team Bravo and Team Charlie are annihilated, and Team Alpha begins fighting. The moment he neutralizes Dione and tries to capture it, Dione flees to the underground waterway.
  5. CF. The LS unit is a combat unit belonging to the Aegis Research Center and is active in all weather conditions such as search, attack, and defense. Alpha, Bravo, and Charlie are dispatched to South America after receiving a report that there is a trace of Dr. Rex, but Bravo and Charlie are annihilated in a battle against zombies.
  6. CF. Prototype Dione, a previously unreported type of Dione, appears to be acting independently without anyone's control.

Tips[]

  • There are several spots which have large rocks in this map, where the player is able to climb onto. If he/she stands above the rock the zombies will be unable to damage the player.
  • Avoid Dione's poison as it deals moderate to high damage, slows down the victim's movement and decreases 30 to 50 of your health points every second.
  • Further information and tactics when facing Dione can be found here.
  • It is recommended not to blow up the wall of rocks before destroying the last barrier, as it will spawn more zombies than usual.
