Wolfenstein II: The New Colossus has a fully playable reskinned version of 1993's Wolfenstein 3D. “Wolfstone” can be found on the resistance U-boat and it’s a ton of fun. You can watch me play some in the video above.
There's no better way to show how much graphics have changed in the last 22 years than B. J. Blazkowicz, the main character of the Wolfenstein games, dressed as a baby. He's wearing the same silly costume in Wolfenstein 3D from 1992 and in Wolfenstein: The New Order. It just got 100% more realistic and frightening.
