Hitchhiking

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

Overview
Hitchhiking takes place in an abandoned silo facility. The humans must escape from the zombies and reach a train at the end of this map. There is a new unknown NPC (Probably Gerrard) and Zim 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. Perhaps, there is a continuous map for this one.

Events
This map was released alongside with AWP-Z on:
 * South Korea: 20 June 2013. Upon success escape, the players can get:
 * First time: Gruesome Assassin (1 day) + Brutal Slayer (1 day)
 * 5 times: Fear Terminator (7 days)
 * 10 times: All above for 7 days

Trivia

 * This map design is quite similar to Survivor, a Counter-Strike: Condition Zero Deleted Scenes mission, Secret War and Tunnel maps.
 * This is the first Zombie Escape map that the player must go through a water pool.
 * Humans and Zombies (even the Origin) can died when riding on the train if not crouching since the tunnel roof is tight with train's roof or if they fall off to the ground. However, the players are respawned near the train to try again.
 * The laboratory resembles Black Mesa in Half-Life.
