Fix: Fallout 3 Not Launching on PC


Fallout 3 is an action role-playing game offered by Bethesda Softworks. The game’s in the market for a long time and it’s can be played via Steam and Epic Games Launcher.

Players can enjoy four different endings of their gameplay. However, it’s nearly impossible to enjoy all four endings at the same time, they need to complete the main story with a different path, to enjoy a different ending.

If any player decides to see all endings, he will have to spend about 23 hours, without having to waste any time. Though, it’s totally worth it, when you get to complete the Broken Steel quests.
