On the heels of the gameplay footage that was revealed at Game XP, Sony have posted a new developer diary for the upcoming remake of MediEvil.

The three-minute clip explores the key aspects of remaking a 20-year old PlayStation classic by referring back to the original development team. “Our credo was: Do what they did, and don’t change anything unless you have a good reason to change it,” said Jeff Nachbauer, executive producer on the remade MediEvil.

“There’s comments in the original source code of what music the developers were listening to at the time they were first making the game, which helped us understand what they were getting at when they first coded that area.”

MediEvil is due out for PlayStation 4 on October 25.
