Hitchhiking (ze_hitchhiking) is the fourth Zombie Escape map in Counter-Strike Online.

Official Description[]

After the collapse of Vanguard Laboratory...

The remaining troops of David Black and Erika have gone missing while they were performing the mission.

Meanwhile, there was a team who retrieved an important research document from the ruined Vanguard Laboratory. An unidentified man and his troops headed to the Polar Regions with the retrieved item. It looked like the plan was working smoothly although it did not have a clear reason and destination.

However, as always, the danger appeared suddenly. They arrived at the wrong destination due to an unknown infection incident while they were heading to the Polar Regions. The unidentified team has been searching for ways to escape as they were chased by unknown creatures and their screaming...


  1. Gerrard is commissioned to retrieve a sample from the ruined and mysterious military facility.
  2. While searching for a mysterious military facility that has been destroyed to retrieve samples, an unexpected harvest finds traces of David Black there and is greatly enhanced.
  3. While moving to the polar region to complete sample collection and deliver samples to the transport team, a colleague turns into a zombie, causing a helicopter crash and being chased by the zombies.
  4. He manages to avoid the zombie chase and succeeds in escaping in the freight train sent by the transport team.


  • Human: Escape to the transportation train in the escape area within the time limit. You must remain as a human.
  • Zombie: Infect every human with the virus or move to the escape area and stop humans from escaping.


Hitchhiking takes place in the Vanguard abandoned silo facility. The humans must escape from the zombies and reach a train at the end of this map. Jim and an unknown NPC are introduced in this map.

Players spawn somewhere outside a silo facility and rushed into the facility. Finally, the human survivors escape via a train in the facility tunnel. The continuous map for this one is Cold Fear.


  1. Everyone, use the steam from the pipe to secure the escape route. Move now!
  2. Fine, let’s provide the electric power to operate this train!
  3. Jim: Survivors at the back, listen to me!
  4. Jim: If you want to survive, run and ride on the next train!
