I cant seem to locate the console command to put the player into invisible mode/no target status (for POI testing, etc.) GOD mode does not make you invisible. Enemies will still shoot at you.
Gm fly (normal God mode) Gm iv (invisible, ai can't see you) Gm ic (God mode without noclip and fly, good for testing internal mechanics of a poi) ai off/on (pauses all ai, including NPCs and turrets) I've found those all useful for testing POIs.
