"Almost 25 years after it was released, Doom 2 has finally given up its last Secret..." writes Polygon. An anonymous reader quotes their report: It's secret No. 4 on Map 15 (Industrial Zone). Now, the area in question has been known, seen and accessed by other means (usually a noclip cheat code). Getting to it without a cheat appears to be deliberately impossible, according to Doom co-creator John Romero. Romero tweeted out congratulations to the solution's discoverer, Zero Master. Zero Master figured out that the way to trigger the secret was to be pushed into the secret area by an enemy (in this case, a Pain Elemental). Apparently the secret sector was an area just below the floor of a teleporter -- but entering that teleporter meant players rose up to the level of the teleporter's floor, according to Romero, so "you never enter the sector... you would never get inside the teleporter sector to trigger the secret." One Reddit user notes Zero Master "has the first legit Doom 2 100% save file on earth, after 24 years."
