|The following is based on S.T.A.L.K.E.R.: Shadow of Chernobyl cut content and has not been confirmed by canon sources.|
Darkscape (or rather Dark Valley escape) is a location cut entirely from S.T.A.L.K.E.R.: Shadow of Chernobyl.
A narrow valley shaped roughly like a crescent moon, it connects the southern edge of Dark Valley with the abandoned tunnel in the Cordon. Roads lead out of the area south and east, although where they exactly lead is unknown. It is a densely forested area with few landmarks, however, several of them stand out. At the end of the most narrow part of the valley lies a collapsed train bridge, part of the railway that passes through the Cordon and the Great Swamp.
Further to the south, the road separates before a hill. To the southwest, deep in the wilderness, lies an abandoned farm house, stripped bare of everything. The main road continues to a crossroads, next to which lies an abandoned gas station. From there, a road leads west, directly to the cordon.
Shadow of Chernobyl
This level was supposed to be a fast-paced escape scenario, where the player attempts to outrun the pursuing Hind and fight through enemy soldiers on the way in order to reach the road back to the Cordon. Groups of Ukrainian soldiers would attack the player on the way, blocking the way with makeshift roadblocks and attempting to take out the vehicle (likely an UAZ) with RPG launchers. On the way, the player would be able to switch vehicles, if his current one became too damaged.
The level is available in Build 2571. It disappeared from the game when vehicles were cut, although it can still be clearly seen on the overhead map of the Zone in Shadow of Chernobyl. In fact, when exiting the Dark Valley, the player is immediately placed in the Cordon, although relative to the exit from the valley, it's a completely different location. One can assume that he simply travels through it offscreen.
