Μafter 24 years, someone was found who managed to unlock all the secrets of the legend Doom II and become the first to complete the game 100%. This is a secret in Map 15 that was originally considered a bug and concerned a teleporter that apparently did not work when the gamer stepped on it.
Eventually, all that was needed was to let an enemy push you into the teleporter! The confirmation came from the game's creator, John Romero, who congratulated the Zero Master via Twitter and confirmed the process for that particular secret.
The gamer did it with the help of a Pain Elemental with which he played the cat with the mouse for a long time until he managed to "eat" the appropriate push in the depth of the teleporter.
