Fallout 3 was released to the world in 2008, two decades ago, and there are still folks trying out the open-world post-apocalyptic RPG for the first time in 2025. If you’re one of those and quickly discovering the dated gameplay, chances are a few Fallout 3 PC cheats could help ease the transition.
From the iconic god mode to turning on NoClip to drift through the world, Fallout 3 cheats can create a genuinely jank yet fun experience.
