Advert#
The October 1984 Konami Computer Software Catalog advertises a disk edition of King's Valley in addition to the ROM version, but also shows some early screenshots as well. Most notably, there is a scorpion enemy not present in the final game, and the cutscene for outside the pyramid is shown at daytime instead of nighttime like the final version.
This advert was later reused wholesale for the February 1985 catalog.
