Valve cache is a stash featured in S.T.A.L.K.E.R.: Lost Alpha.

It's a good place to hide something small and valuable, though the hole grid around you makes you think twice..
- PDA description


  • The stash is located in the pipe that had a Soul as a possible stash item in the Base Game. The area is not radioactive.
  • There are a pack of Blind Dogs in the area.


  • Obtaining any coordinates in Lost Factory is problematic due to the low NPC population.
  • There could be a failed recon unit in the lake which may be able to provide information.
  • The Mac 10 is cut content for the unmodified version 1.3003 game and consequently will not appear in the stash.


  • Hound, the brother of Wolf is one of the casualties in this expedition.
