A lot of people are unhappy with Homeworld: Deserts of Kharak's 1.4 update, which added Epic Online Services, and due to either a buggy implementation of EOS on the part of BBI, a bad Unity EOS plug-in by Epic, or a combination of the two, broke the ability to play DoK completely offline in campaign or skirmish modes.

Luckily, Steam keeps every version of a game in its backend, and it's possible even for regular schmoes who don't work at Valve or BBI to access them if we know what we're doing.

Here's how to do it!

1. Access the Steam Console by pressing the Win+R and running steam://nav/console
   
2. In the new Console tab that has become visible in Steam, enter the following:
   
3. download_depot 281610 281611 5547161778067914449
   
4. Wait for the Steam Console to show the download is complete then enter the following to download the 32-bit Windows executable:
   
5. download_depot 281610 281612 124447714406548962
   
6. Enter the following to download the 64-bit Windows executable:
   
7. download_depot 281610 281613 482984376389592123
   
8. Navigate to Your Steam Install\Steamapps\content\app_281610
   
9. Copy the contents of depot_281612 or depot_281613 into depot_281611
   
10. Navigate to Your Steam Install\Steamapps\common\Deserts of Kharak
    
11. Delete everything in this folder except for installscript.vdf and steam_appid.txt
    
12. Copy the contents of the merged depot_281611 folder into the Deserts of Kharak folder.
    
13. Rename DesertsOfKharak32.exe or DesertsOfKharak64.exe to DesertsOfKharak.exe
    
14. Launch Deserts of Kharak. Revel in the lack of Epic Online Services
    
15. Quit Deserts of Kharak and shut off your internet and launch it again and play if offline if you want.
