Blood alpha (February 6, 1996) m1.map (with added enemies and restored early skybox texture)
The oldest levels of Blood Alpha Demo are pfgear.map (August 29, 1995) and m1.map (October 4, 1995). Unfortunately pfgear.map use an ancient BUILD format unsupported by any editor.
Video shows m1.map with added enemies (they are not available on the original version of the map, but they can be seen in the editor) as well as the restored early skybox texture, cleared of "REPLACE WITH TILE #2500!" put over its texture.
In this map, the use key doesn't seem to work. This means that doors cannot be opened and switched cannot be pulled. Most likely it was due to some kind of core change to sector functions with levels not being updated
