Polikhim hobo? The former security deputy chief? Yes, I knew him. All this mess caused him some massive damage - took to drinking, degraded to a hobo. And he wasn't a bad guy... Wait a sec, can't he say for himself? Got whacked or something? Well, doesn't matter, apparently, once you ask, then there are some problems. Well, I knew where he lived, but here's the deal - I need help scaring off the Scavs from the Customs. If you help me, I'll tell you where this hobo lived.
Thank you, warrior. Well, your hobo used to dwell on the railway, on the train car next to the boiler. My guys have seen him there often. See you later.
Despite the quest's purpose of giving you information for Skier's quest Chemical - Part 1, if you complete Skier's quest before finishing Polikhim hobo, it will not cancel the quest.
In previous patches, this quest used to have a time limit of 2 hours while still requiring you to kill 25 scavs on Customs.
