Section 1: Prepwork
Please do the following:
  1. Backup all the files at <PD3>\PAYDAY3\Binaries\Win64 into a separate folder. This is for easy retrieval and reversal.
    This can be done by navigate to your installed location on your PC. If you're unfamiliar where they are, you can use Steam's Library to right-click Payday 3 and browse local files, then navigate to PAYDAY3\Binaries\Win64 manually.


  2. (Optional) Enable modding for Payday 3.
    It's not strictly required to play offline, but allows you to replace the blinding white background with an actual image, plus the ability to pause and restart heists when solo offline.
    To do so, open Payday 3's properties, similarly to browsing local files, then add
    -fileopenlog
    to the Launch Options. Please refer to both images if needed.

Section 2: PayCheck3
Please do the following:
  1. Please download a copy of PayCheck3[github.com]
    This is a slightly involved process, but as far as I know only one simple change needs to be made to one file afterwards to reverse it and restore you back to online gameplay. I will illustrate the directions below.

    It is RECOMMENDED to use the "release" build, which is most directly linked above. Those of you willing and more talented with computers can use latest artifacts (you'll likely know what that means).


  2. Begin installing PayCheck3, admin privileges required from this point forward
    You can store PayCheck3 wherever you want on your PC. I will try to be as clear as possible, if you ever have trouble parsing my directions try referring to the readme.txt in PayCheck3\Cert\readme.txt and the PayCheck3 Github readme.[github.com]

  3. Extract Paycheck3 anywhere of your choosing, then run "run.bat" in the Cert folder

  4. Install the cert.CRT file generated in the same folder as "run.bat". Refer to the image below and follow the numbers


  5. Next, install the cert.PFX file. Refer to the image below and follow the numbers


  6. Copy the CRT and PFX files out of Cert folder and paste next to PayCheck3's executable, one folder up

  7. Find and open your hosts file (Notepad or better)
    A quick way to reach your hosts file on Windows is to copy
    %systemroot%\System32\drivers\etc\hosts
    into your Explorer path, and open hosts with your text editor of choice (Notepad works fine).

  8. Edit your hosts file
    Add the following to the bottom of your hosts file
    127.0.0.1 nebula.starbreeze.com # PayCheck 3 Server emulator 127.0.0.1 connectivitycheck.gstatic.com # PayCheck 3 Server emulator

  9. PayCheck3 is ready for you! But the guide's not done yet!

Whenever you intend to play online/normally, place a # in front of the IP addresses (127.0.0.1) and save hosts again to undo it redirecting to your local PC.
Section 3: PD3 UE4SS, DebugMenuMod and More
If you got through section 2, this part should be a cakewalk in comparison.
Please do the following:
  1. Download a copy of PD3 UE4SS[modworkshop.net] and install
    Copy all the files to your <PD3>\PAYDAY3\Binaries\Win64 directory. You should have already backed up the original files in Section 1 for easy retrieval and reversal. If you did not, you can delete all contents of Win64 and verify Steam cache to recover original files, then backup and install PD3 UE4SS.

  2. Download a copy of DebugModMenu[modworkshop.net] and install
    Put the DebugModMenu folder in <PD3>\PAYDAY3\Binaries\Win64\Mods, the new Mods folder you copied in from PD3 UE4SS.

  3. (Optional) Download a copy of Fix Old Heist Selection Menu[modworkshop.net] and install
    This is not required, but it replaces the searing white background of the old heist selection menu with a less flashbanging image. You also needed to enable modding as per Section 1 of this guide.
    Navigate to <PD3>\PAYDAY3\Content\Paks and create a new folder called ~mods folder, then put the zFixOHSM.pak file within.
  4. (Optional) Download a copy of Solo Game Utils[modworkshop.net] and install
    Installs identically to Old Heist Selection Menu, and also comes with a replacement image, but adds the ability to pause and restart the heist offline.
  5. Payday 3 is modded for offline solo play!

Whenever you intend to play online/normally, you MAY need to remove Solo Game Utils from your copy, or just ignore the buttons. I actually don't know if they do anything online, sorry!
Section 4: Playing Offline!
All modifications are done! You can now play Payday 3 solo offline!
Please do the following:
  1. Launch PayCheck3's Server Emulator

  2. Launch Payday 3 through Steam

  3. Once logged in, navigate to the More button (far right) and click Old Heist Selection

  4. Pick the heist of your choosing, then click Play Solo

  5. Keep them helmets flying (hopefully) into perpetuity!

When finished, type and enter Q into the Server Emulator window to shut it down.
FAQ: HELP!
This will be a little barren to start, just trying to answer immediate questions that come to mind.
  • Will any of my online progression be here?
    No.
  • Will anything I do offline with this method travel with me online?
    Strongly doubt it.
  • Can I earn offline local progression with this setup?
    Not sure yet, feel free to let me (and others) know if it does though!

Also MASSIVE thanks to the hard working heisters SlejmUr, Narknon, Florens, Abkarino and anyone else I failed to mention here who have worked to make these tools and mods! For all of you, I wish for your drills to never jam. <3
