Kostya's stash, Radar

== Walkthrough ==
After taking this stash, you'll be teleported into the Rusty Forest at Radar, and 6 zombified stalkers will spawn around.
All four variants are shown on the video.
Report to Kostya. Kostya will decrypt PDAs from all these stashes, and devise the different parts of the code: 9, 7, 2, 54, 61. The clue on how to arrange these numbers into the code should be in X-10 itself, in the final stash. He also says that the increased activity of bloodsuckers has been reported in X-10, so you should bring a good weapon against them.
== Notes ==
* Kostya's warning is fair, and you'd better wipe the entire laboratory out before accepting the next quest in the series from him.
