The Crash To Desktop (CTD) issue was a bane for many who wanted to play this game offline (in Steam via uPlay) and yours truly gave up for several years until the remedy was found in the Steam discussion forum. Let's not dwell on the problem and get to the solution!

Without further ado, follow these steps below:

1. Navigate to the installed location ..\Steam\steamapps\common\Tom Clancy's Splinter Cell Blacklist\src\SYSTEM

2. Locate Blacklist_Game.exe (for DX9) or Blacklist_DX11_game.exe (for DX11)

3. Create a shortcut for whichever exe version to be use.

4. Right click on the shortcut and select Properties.

5. Add this command at the end of the target -offline -offline_mode
so it will look like this: "..\Steam\steamapps\common\TomClancy's Splinter Cell Blacklist\src\SYSTEM\Blacklist_game.exe" -offline -offline_mode

6. Save it and launch the shortcut and it should be golden to play Offline now.

Note: The Offline -offline -offline_mode can also be used in the Steam Launch Options and passed to uPlay during game launch. Remember to remove it when playing Online though!

Now go have fun like I did after 4 years of CTD and finally uninterrupted offline play... Sweet!
