NewYzSOD is a map set for shareware Spear of Destiny, made by Alex Gilchrist. It was released on June 26, 2001.
Never being hosted by Brian Lowe, it was only available on Alex' own site. As with the original YzSOD, this features mapping of low-end quality and uses only skill 1 guards.
A map set, it is playable in SDL.
