From GameWatcher: “Mr. X mods are quite popular among the Resident Evil 2 Remake community, letting players live out their fantasies of being chased around Raccoon City by brutes and non-brutes from other IPs.
One of the most recent Mr. X mods replaces him with none other than Darth Vader himself, giving players a sense of what it must have felt to be a regular Rebel soldier running from the Sith Lord.”
