Version notes and help
Supercharged gravity-gun caveat
The special gravity-gun setting changes more than its appearance. It can alter what happens to NPC weapons and make ordinary encounters behave unlike the intended chapter. Use it for a sandbox experiment rather than a clean progression save.
Getting unstuck
Disable noclip only after returning to open floor. If a companion or scripted event was left behind, loading the pre-cheat save is more reliable than forcing farther ahead. A command that changes player movement does not complete story triggers.
No automatic story completion
Equipment grants do not complete chapter objectives or move companions through their scripted sequences.
Common questions
Do console commands preserve achievements?
Keep a separate normal run. Enabling cheats can prevent achievement progress during the session.
How do I turn cheats off?
Disable individual toggles, enter sv_cheats 0, and reload an untouched save for normal progression.
