A glitched location; quests are either not accepted or not completed right away. Near the entrance, Lenny the ghoul stands next to a corpse, hoping his friend will come back to life. You can explain the absurdity of his expectations, but there's a more interesting option: talk to the ghoul repairing the guardhouse at the entrance and swap him for Lenny's friend's corpse. And—you've worked a miracle: the "corpse" comes back to life, and Lenny rewards you with a decent shotgun, the Wild (though I've been carrying exactly the same one for a while now).
Enter the bar; the Healer is standing behind the counter, the Shepherd is closer to the stage, Douglas is at a table, and in the next room, by the door to the drug lab (trying to open it is useless), stands Kent.
You can start by talking to the Healer and learn that they produce a powerful drug called "Drip." Then, you should talk to Douglas, show mistrust, and learn the coordinates of Army Headquarters, while also accepting the quest to find his dog tag. We go to the ring on the right side of the location and pick up the dog tag during the fight. You can also choose to do so without a fight, if you have a good conversation.
At the beginning of the conversation with the Shepherd, you'll be faced with a dilemma: help the girl or turn her over to the guard (which she generally deserves). The first option involves a fight with the Shepherd, followed by a showdown with the Boar. If your communication skill is high, you can explain to him that the Shepherd was the weak link in the Boar's gang, since he couldn't handle one whore, and the Boar appoints the protagonist to his position. This will eliminate the interesting option of infiltrating the drug lab, so don't interfere. Afterwards, the Shepherd will offer to have some fun with the girls. In their restroom, in the left corner, there's a box with interesting contents. Furthermore, after "chatting" with the girls, the protagonist's satisfied face temporarily increases Charisma and Luck.
Talk to Kent, jump straight to the job, accept the quest for mutant ant abdomens, and learn that they're used to make a drop. Go to the entrance to the location and turn left into the cave. Hand it over.
Hand over the goods to the Healer (and the quest to Kent), and a thread about Douglas will appear—find out who he is and whether he poses a threat to the local "business."
Return the token to Douglas, talk again, and learn that he works for Olympus, and there's a list of things you need to find and bring there. Steal the list and the token from Douglas. However, it's best not to mention Olympus in the conversation with the Healer, instead saying that Douglas is just a struggling adventurer and poses no danger. The Healer will give you the drug Admiration—a quest item for entering Olympus.
Return to the Shepherd—his girls are being bothered by Boar's confidant, Brick, who guards the entrance to the building below the ring. We go to Belka and Strelka, the prostitutes at Boar's, and coax them into having sex with the sexually obsessed character. We go to Brick, who leaves in anticipation of pleasure, and access to the building is unlocked.
There's a hatch in the left room; we go through it and enter the drug lab. There, we talk to the girl in the white coat about everything and offer her an escape. We leave the same way.
We can get to the main point - talk to Kent about him, his outfit, the fact that a fish rots from the head down, and offer to eliminate Boar. He'll do it himself.
Now to the Healer. The King is dead - long live the king. We offer to eliminate Kent, then go to Belka and Strelka and instruct them to poison Kent's food. After a while, or several, by talking with the Healer and the prostitutes, we become the local drug lord. The front door to the drug lab will only open now.
You can also rob caravans; an NPC near the car below the ring will give you an invitation, but what's the point?
Army Headquarters:
Take out a dozen bandits, open the wall safe (similar to repairing the transformer in Tartarus), and take the access card to the Tartarus-Olympus elevator.
Also, hack the storage locker or disable the generator by repairing it and take Barak's rifle, a quest item for Olympus.
Renaissance:
Find a hidden passage in the rock – the cursor will change to a hand.
In the toilet, in the upper left corner, you'll find an Intellect Potato.
In the lower right corner, there's a robotron; it needs three sets of Big Bat batteries.
One of the cabinets contains a porn disc, but its purpose is unclear.
Return to Tartarus.
To do this, simply get the Herald's Cassock from Mangy Dog, and you'll be able to proceed through the Metro Station.
To save your father, you'll need RadAway, which can be purchased at Rainbow.
You can talk Smitty into it, or exchange sugar and tin for the methods of crafting homemade grenades and a rusty cuirass – who needs them when you already have plenty of armor and weapons?
Ask the doctor for help with his patients – you need to run through the residential sector, the farm, and the technical floor and heal everyone lying around and moaning. No problem, the doctor will share his medical knowledge or medications in exchange.
The story requires talking to Gregorius. He'll tell you that you can get to Olympus via the elevator. You'll need a map. It's in Army Headquarters, and the seeker Douglas has gone to get it.
If you didn't send Katie's father to the Mouth of Hell, you can talk to her—but apparently, after the outside world, she didn't impress the main character. That's all.
