They faked an entire subway system... 💀

These developers faked an entire subway system, and players fell for it for years. When Bethesda added a working metro to Fallout 3’s DLC, nobody questioned how it worked. The truth? The game engine couldn't handle actual vehicles. Building a functional train was literally impossible — so they faked it. When you board the metro, the game forcefully equips the subway car directly onto your head like a helmet... and locks your controls as you invisibly run down the tracks.
