Wolfenstein: The New Order ➔ Wolfenstein 3D

The modern Wolfenstein games are almost unrecognizable compared to the franchise’s origins. Beginning in 1981 and ‘84 as a stealth-action game for the Apple II, the series was then revived by a pre-Doom id Software as 1992’s Wolfenstein 3D
While Wolf 3D was certainly not the first first-person shooter as it’s oddly credited all too often (that honor goes to 1973’s Maze War), it was absolutely the game that made the genre authentic. Almost 30 years later, it’s still an enormously playable and entertaining game, as was discovered by those who found the not-very-well hidden Easter egg in 2014’s The New Order.
Once you’ve reached the resistance headquarters in The New Order’s campaign, have a poke around upstairs and you’ll discover a makeshift bed in the loft, on which you can take a nap. Do so, and you’ll dream you’re playing Wolf 3D. By, you know, playing it. It’s just the first level, and even more strangely you still have your New Order weapons and healing, but it’s no less a delightful surprise.
