how to cheat in this game does
This is not your garden variety of Renpy or RPGMaker game, so cheating is tricky. The "console" by F12 shows some sort of html+JavaScript, so forget about it too.
Sometimes I got the bug which allowed me to
noclip all (usually happens inside the vault). Go to Journal and play a sex scene, then interrupt it Esc and end it. My char was noclipping till next sleep. It fails to work when it's trully needed.
For cheating try CheatEngine. External software. Never run Steam or Battlenet when it's running or get banned forever.
You can edit "life" points (HP), EXP (level only increases MaxHP anyway), Nr of Inventory items (when trading) eg Stimpacks (then barter them for BottleCaps).
The trick is to select THIRD exe-file process as game runs 3 at the same time, but stores relevant values in the bottom most one.
Search for HP like:
4Bytes by
Exact Value
example you have "30" hp so Search "New Scan" for 30 (you will get around 2000+ addresses), then fight or heal and search for changed value by NEXT SCAN with changed value say 26 (will decrease said adresses to eg 200). Repeat till you have 1 address which you can change.
Giving yourself 900 hp will do nothing as when enemy attacks you the HP will reset to Max HP value.
Remember to save often.
