Fallout: New Vegas — No Official Invincibility Cheat, But PC Console Commands Exist

There is no official "invincibility" cheat code for Fallout: New Vegas. However, PC players can use console commands to achieve near-invulnerability:

• tgm – Toggles God Mode (immune to damage, but not environmental hazards like falling).
• player.setlevel 255 – Sets level to maximum, granting massive health and damage resistance.

Warning: Console commands can disable achievements and potentially corrupt save files. Always back up your saves before experimenting.

For the intended experience, embracing the game's challenge is recommended.
