Half-Life: Alyx Workshop Tools/Modding/Source2mod/Saving maps ingame
Usage
To allow games to be saved by the user through the UI, insert this prefab into every map of your mod.
Trivia
Source 2 no longer supports the -hijack command, so the UI creates a hijack.cfg inside the cfg directory and this prefab keeps trying to execute that hijack.cfg. Once it's executed, the UI detects it and erases afterward.
