Why do I think there's a secret on E1M1?

Alright, I'll tell you. It's DWANGO11 Map12.

Kinda like this, I distinctly remember the switch room in map 2 to have two bar doors, the red one on the right and a silver one on the left. Maybe it was my young mind playing tricks on me or something.

Is that Doom II's map 2 you're talking about? The early Doom II versions does have those silver bars to the left you're probably referring to. I'm not sure why they were removed in later Doom II versions.

For the same reason that the entire map was shifted a few map units to the right, without moving any of the Things, resulting in the "famous" stuck shotgunner. That reason is...well, I'm not sure anybody really knows.

It did, in v1.666 - it also still has them in Doom II for GBA.

Ah okay. That explains it.
