For those who experience crashing every 20-30 min randomly without reasons:

1. Navigate to the Splinter Cell Blacklist "SYSTEM" folder.

2. Locate Blacklist_Game.exe or Blacklist DX11

3.Create a shortcut on your desktop for whichever version you want to use.

4.Right click on the shortcut and select Properties.

6.Add this command at the end of the target -offline -offline_mode

so it will look like this : "C:\Program Files (x86)\Steam\steamapps\common\Tom Clancy's Splinter Cell Blacklist\src\SYSTEM\Blacklist_game.exe" -offline -offline_mode
