Twenty-four years were needed for the last secret to be found.
John Romero, one of the former iconic faces of id Software, worked on several FPS titles, all of which could be called revolutionary even today, including Doom 2. He knows Doomguy from all aspects, and he congratulated Zero Master on Twitter for finding the last secret on the Industrial Zone map (level 15).
„CONGRATS, Zero Master! Finally, after 24 years! “To win the game, you must get 100% on level 15 by John Romero.” Great trick getting to that secret! Secret explained: A secret teleporter is marked as a discoverable “secret”, but when you touch it, you never enter the sector. So you would never get inside the teleporter sector to trigger the secret. The only way to trigger this secret is to be pushed by an enemy into it,” Romero explains on Twitter.
This discovery means that Doom 2 can be now completed to 100% without any cheats (idclip, iddqd, and so on…). Watch the video below from 02:30 or so, and the secret gets activated at 03:04. id Software‘s game finally „gave up” – it only needed roughly a quarter century…
