It's tough to determine what's more impressive here: the fact that people are still playing Doom II after nearly 24 years or the fact that it took this long for someone to figure out how to activate the game's last remaining secret.
A Doom 2 fan has discovered the game's final secret nearly 24 years after its release, winning praise from the series' co-creator.
A player going by the name Zero Master posted a video on YouTube -- first reported by Rock, Paper, Shotgun -- revealing how to unlock the secret in the first-person shooter's 15th level. This was previously thought to be impossible due to a bug.
As Zero Master explains in the video’s description, the secret location on map 15 (Industrial Zone) has long been known but was thought to be impossible to trigger naturally without cheats. Until recently, the DoomWiki for the secret read as follows:
“It is impossible to register secret #4, as the secret sector in question (sector 147) is located adjacent to the raised teleport pad and is only 16 units wide. This setup completely prevents the player from touching this sector's floor (as is required to trigger a secret), because upon crossing the sector's boundary they are immediately raised onto the pad and teleport away. Therefore, the maximum SECRETS percentage one can get on this map is 90%.”
Experts have known the location of this secret, but couldn't access it without cheating… until now.
"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!" co-creator John Romero wrote on Twitter.
