Hello. Can someone give me the following info:

- Was Catacomb Abyss (1st part only) released by ID Software?
- Was it released before or after Wolfenstein 3D?

according to this, it was released in 1990 by softdisk

It says 1992.
Hmm, not ID software. I guess I won't mention it in the book I'm currently writing.

http://rinkworks.com/apogee/s/2.7.2.shtml is a decent explanation of how SoftDisk fits into the picture. Catacomb Abyss is discussed near the bottom of that page.
