Like CLAUS, this level is very small and doesn't have an in-game name. It also has no documentation, meaning we must rely once more on the filename (which is why it is capitalized, because levels for Quake tend to have capitalized filenames). This is a practice similar to the Doom naming of levels, though I remove the filename seeing as it is pretty pointless as we know what we are talking about. So, you don't need to know it is DOORH.BSP, as DOORH is adequate for these purposes.
Why does this level exist? This seems like something somebody might have made to test their ability to make a Movable Wall. If that is the case, why was it ever release to the public? Why was a test map included with Aftershock? We are now taking shovelware to an entire new plane of existence, one where there is a minimal amount of content. Even Q2 didn't pull this sort of stunt, whereby test maps were included just to appear to have a larger number of files.
