Using the vent that’s leaning down, you can climb atop the roof of this building.
Going up there can lead to sequence-breaking within the map. :fffuuu:
Wasn’t that able to get on the roof also in Half Life?
In half-life, you enter that building on the roof. In Black Mesa, you come in through a top-level fire escape.
Can you do anything once you’re up there like skip the level or launch yourself into the skybox? If not I don’t see a problem.
