Documents from Lab X18, part 3

 is a storyline quest item that appears in S.T.A.L.K.E.R.: Lost Alpha. "After yesterday’s breakout in the animal pens, it has been decided that we’re locking the place up and are going to gas them up. Ivan has come up with something that will kill these - well, whatever you weirdoes have been stitching together. Consider this a fair warning; next time, the mutants aren’t going to be only thing getting gassed. First we had the incident that killed Dolovan, now this. I expect better out of meticulous men such as yourselves. You’re all on forced leave until we filter the place out. Look on the bright side: you can have fun with the corpses."
