  1. 1
    Clear the blockade and exit the party.
  2. 2
    Ignore Zombies (Zs), use the gravity gun (GG) to move past them and up the stairs.
  3. 3
    Meet Papa Grigori and locate the gas tank near the building's entrance (EP). Turn the valve to kill the fire.
  4. 4
    Enter the building, use the GG to move through room #1 to the stairs.
  5. 5
    Drop the explosive barrel (DB) at the base of the stairs.
  6. 6
    Use the GG to move bureaus to block access to the stairs.
  7. 7
    Proceed up the stairs, using the GG to move Headcrabs (HCs) or avoid them.
  8. 8
    Locate room #2 with the bureau blocking the exit (XP). Sprint and use the GG to move the bureau.
  9. 9
    Sprint through room #3 and into room #4. Pull the lever on the wall near the window.
  10. 10
    Sprint back to the top of the stairs, maneuvering around 3 Zs.
  11. 11
    Use the opening at the head of the stairs to reach the overhead walkway in room #1.
  12. 12
    Maneuver for a clean drop onto the machine on the lower platform.
  13. 13
    Use the GG to move DB and exit.
  14. 14
    Outside, use the junked car to jump to the top of the retaining wall.
  15. 15
    Proceed to gas tank #2, locate the valve, and turn it.
  16. 16
    Launch DB over the fence and weave through 3 full and 1 partial Z to the ladder.
  17. 17
    Climb the ladders and planking into the 2nd floor of the next building.
  18. 18
    Enter the room with Zs and HCs on the ground floor, drop DB to them.
  19. 19
    Use the GG to remove boards from the XP. Reacquire (RA) DB and exit the building.
  20. 20
    From your position, handle the 6 local Zs.
  21. 21
    Proceed to the lever of car trap #2, drop DB near it, and pull the lever.
  22. 22
    Quickly hop onto car #2 before it rises too high.
  23. 23
    As the car stops, RA DB. Move over the car and planks into the 2nd floor window.
  24. 24
    Exit the 2nd floor room to the room with explosive barrels (EBs) and a spider.
  25. 25
    Advance on the spider while holding DB; it will lodge itself against your XP.
  26. 26
    If the spider lodges in the XP niche and DB is nearby, the door will only open into the walkway. Drop DB prior to the XP niche to give the spider room to exit.
  27. 27
    If the spider moves back into the walkway, enter the room, RA DB, and close the door.
  28. 28
    If the spider refuses to move away, kill it.
Tips
  • If you don't move or detonate the EB at the base of the stairs, it can explode and destroy DB.
  • Grigori may or may not shoot any of the Zs with this approach.
  • There's always a route through the mess, sometimes convoluted, but it's rare for a Z to make it into the short hallway. If it does, you can DB it or backstep and lure it to one side then end run it.
  • It is a rare occurrence to have a Z in the short hallway. The Z can be drawn to a side of the hallway; backstep a few feet to make space and prevent the 2 PS from dropping down, then pick a wall to hug. When you have drawn it away, sprint by it, you may take a hit or 2.
  • DB has problems riding car traps up; if you hold onto DB as the car raises, you get dragged off. Once car #2 is at a stable elevation, DB behaves.
  • There are new kinks with retrieving DB from car #2 due to game updates. If DB is near or directly below the rear bumper, you can GG it but lose grip above the ground. After a few tries and Z interference, it moves far enough away to come up.
  • Invisible barriers may prevent DB from completing Nova Prospekt, possibly due to a Steam patch/update.
  • Methods for dealing with Zs and DB:
    • Kill all and launch DB through the 2nd floor XP.
  • Kill 6, evade 3, and launch DB through the XP.
  • Kill all, leave DB on the ground, then pull it up from planks or cars.
  • Leave all Zs be, drop DB near car trap #2 activation lever, activate car trap #2, sprint to and jump onto the trunk before it rises. Ride car #2 up, RA DB from your new vantage point.
  • When the spider lodges itself in the XP niche and DB is nearby, the door will only open into the walkway. If you drop DB prior to the XP niche, the door may open into the room or the spider will move back to the walkway.
  • Don't waste much time on the spider for the sake of minimum kills.
