In-depth description
What tgm does
tgm (toggle God mode) makes the player completely invincible. While it is active you cannot take damage, your ammunition and Action Points never deplete, and your carry weight is unlimited so you are never over-encumbered.
How to use it
Open the console with the tilde key ~, type tgm, and press Enter. The command is a toggle — run it once to turn God mode on and again to turn it off.
