— Singapore/Malaysia description

Sidewinder (hs_sidewinder) is the fifth Human Scenario map mission in Counter-Strike Online.


In this map, you must annihilate a certain number of enemies in given limited times. There are 10 rounds. At the last round, XT-300 Goliath will appear as the boss. Destroy it to win and receive either Comanche Record Device, Pilot Tag or Drone Control Chip items.

Official Description[]

We might be annihilated due to the sudden attack from Drone during the airplane transportation if not for Red Lizard Jim, who allow us to ride onto the Blaze. Secret reports were obtained that Norman, the guy Jim trusted the most, has betrayed the mercenary.

Jim looked very anxious after he heard that his base camp has been attacked.

We have decided to leave early as we had to transport the samples safely. We will, hence, reorganize our remaining support troops and dispatch them to the base camp.

- From the diary of the transportation supply troop, Commander Victor.


  1. Due to the betrayal of Jim's right-hand man, Norman, the garrison of the Red Lizard mercenaries is taken over by the Vanguard Company.
  2. Victor's unit is urgently tasked with transporting corpse samples, but in order to repay the kindness of Jim who helped him, he leaves for transport with 3 squads left.
  3. However, shortly thereafter, Victor's troops are stolen by a surprise attack and a sample of the prototype Phobos's body is stolen, and they advance to the Vanguard Company's secret base to retrieve the sample.
  4. Squad 3 and Jim decide to drive out the Vanguard Company from the garrison, defeat the giant XT-300, and pursue Victor.
  5. CF. The XT-300 Goliath is a humanoid combat robot being secretly developed by the Vanguard Company. It is equipped with flamethrowers lethal to infantry and multiple missiles to neutralize bunkers.
