Some believe 1.5 contained an early version of the Resident Evil Remake’s Crimson Head mechanic—zombies that revive if not burned. The Magic Zombie Door, they argued, was a stress test. The door was the only exit, but the game would keep throwing zombies until you died.
Counter-evidence: No burning mechanics exist in the 1.5 code. Additionally, the MZD zombies do not revive. They stay dead. New ones just appear.
In 2018, a complete (though still unstable) 80% build of Resident Evil 1.5 was anonymously released. Known as the “Hall of Fame” build, it allowed dataminers to crack open the game’s original .EVT (event) scripts. resident evil 1.5 magic zombie door

The Magic Zombie Door was not a bug. It was a puzzle. A survival horror riddle with no combat solution—only patience.
The simplest theory: the spawn trigger for the “next zombie” was set to activate every time the player’s collision box touched the door’s trigger zone. Because the level designers never linked the spawn to a variable that turns off after a certain number of enemies, it loops forever. The code is clean
Counter-evidence: The zombies don’t spawn in random locations. They spawn exactly 512 units behind the player’s last position, regardless of where you stand. If you stand in the middle of the room, the zombie spawns in the middle. This suggests intentional design—a dynamic spawn system, not a bug.
