Activate noclip mode
Imagine being at the bottom of steps and making your way up only to find a solid wall in front of you. Why, oh why did the construction guys do this? Is this some sort of elaborate prank to get people to bump their noses on hard surfaces? If so, that’s oddly specific.
We’d like to imagine that there was a door at the top of this staircase to nowhere in the past, but they closed it off for no reason other than to mess with people. Well, they probably weren’t banking on us knowing how to turn on noclip mode. Jokes on you!
