A PC mod has replaced Resident Evil 2's terrifying Mr. X with an even scarier sight: Thomas the Tank Engine.
The mod - which is available now on Nexus Mods - replaces just the visuals, so for the complete and thoroughly terrifying experience, you might want to take the author's suggestion and switch the sound files, too.
In the description, the author just says: "Honestly, I dont know why i made this."
