Did anyone else get this terrifying encounter?

[Adeno]

Yeah I remember this part and actually....

Spoiler below!

If you didn't open that door where the monster is in and you proceed to the end of the next hall with a room where you grab the two remaining elevator rods, when you go back out, you'll encounter the monster a few times. When you get back to the area with the two doors, you'll notice that the door is now open. It's not broken down, suggesting that the monster might actually have the intelligence to open doors properly lol!
