Old documents: part 3

Bring Akim four old documents from Dark Valley and X-18.
== Walkthrough ==
One document is located on a body of a military guy on a factory chimney in Dark Valley. Others are in X-18. All locations are shown in the video below:
== Notes ==
* This quest has great rewards for the early game, so you'll probably want to complete is as soon as possible. APS is the best early pistol - it's full auto, has almost no recoil, and is very similar to an assault rifle in practice (and is more accurate than many), but occupies the pistol slot and lets you spam cheap 9x18mm ammo like crazy. Snotty Porcupine and Tears of the Chimera provide great radiation removal (-75Ci total) at the cost of some bleeding and fatigue, which can be countered by early artifacts from Collector's stashes.
== Bugs ==
* One of the documents spawns on a corpse. It will turn into a zombie in a few days after accepting the quest, rendering the actual document unobtainable and softlocking the quest.
