Lab X14 is a major location appearing in the S.T.A.L.K.E.R.: Lost Alpha standalone Mod.
Well, that place is a restricted area, and we think there are or were nests of these mutants down there. But I tell you what, if you go down there and clear the place out, I won't ask any questions and turn a blind eye. Deal?

  • Probably the smallest lab in the game.
  • It is located underneath Rostok Factory, with its entrance found just down the road from Duty HQ.
