Back before Cyberpunk 2077 released, CD Projekt Red promised an immersive and living city that players could explore a multitude of ways. One of the ways originally showcased in trailers and other promotional footage included the city's subways and monorail systems. Unfortunately, like much of the final release, the actual in-game metro system left a lot to be desired. There were no cleverly designed train rides or even anything of the sort. Instead, Night City's metro system was basically useless. A new mod for Cyberpunk fixes that, though.
