How to unlock the Sonia Belmont skin
Quick answer
Enter the Konami Code: Up, Up, Down, Down, Left, Right, Left, Right, then A, B on Xbox, Cross, Circle on PlayStation or B, A on Switch. It works from the main menu as soon as the game boots, and a "New Character Skin Unlocked!" notice confirms it; then open the menu, go to System, choose Character Skin and select Sonia Style Costume.
