There is now a Multiplayer Nox Demo on PC Zone, with a playable version of Westwood's isometric-view action game that is due in stores next week. The demo is a 44 MB download, and here is the description from the page:

You are the 20th century savior of Nox - summoned to the land in a cosmic accident. Being from Earth, you are the only living being on Nox that may touch a magic Orb in the possession of the wicked-evil queen of the undead - Hecubah. You must find this Orb and harness its power in order to construct the staff of oblivion and defeat Hecubah.
