@sutinoer I wish! I liked Corridor 7 a little bit too much.

Now we need Corridor 1-6!
Did this games exist?

All of these sprites (and a still pending zip full of sprites, flats, and textures) are all of the graphics in the source code for the unfinished Corridor 8 by Capstone before they went defunct. The only graphics not included are curiously present Doom sprites (including three Doom weapons, two enemies, the player character, and even Doom's title image).

Also worth mentioning is that the included palette has the color values lowered to nearly black, with only enough distinction in color values to allow for an in-engine contrast/gamma modifier to make sense of the colors. Because of this, I had to set the values of the color palette myself, for each of the individual 256 colors. Because of that the palette may not be precisely how it would appear in game, but instead just based on a leveling of the actual palette so the sprites don't come out as black.
