It has taken 24 years but a speedrunner has just uncovered Doom 2’s best-kept secret.
Doom speedrunner Zero Master has uncovered an area that was thought to only be accessible via cheats. The previously inaccessible sector is found in the Industrial Zone map, which was designed by John Romero.
Even the Doom wiki had noted that it is impossible to get to this secret area, thus “the maximum secrets percentage one can ordinarily get on this map is 90 percent.” Now we know it is possible and the wiki has been updated.
John Romero personally congratulated Zero Master and explained the process:
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! #doom
