Our (Toxic Zombies) UNDEAD demo was actually reviewed in the UK computer
magazine PC FORMAT in August of 1993.  Bart of Witan was kind enough to send
me a copy of the magazine which contained the article.  Here is what it said:

UNDEAD DEMO
Public domain by  
The Toxic Zombies
Available from PCIUG

BREAKING THE MOULD COMPLETELY, this demo from The Toxic Zombies doesn't have a
single hard-core rave track in its collection of three tunes.  Instead, the
programmers, obviously a chilled couple of dudes, have opted for mellow
ambient tracks to soothe your aching, hard-core blasted brains.

The music on this demo is enjoyable, well constructed and original, but is at
odds with the accompanying graphics and the scrolling text.  The title and the
name of the programming crew give the nature of the demo away; the graphics
are dark and dreary, featuring zombies and skeletal figures.  The scrolling
text explores a confused philosophy regarding death and dissatisfaction with
life.  It's great to see something original, rather than the standard hard-
core music and psychedelic graphics, and this is worth checking out if you are
tired of the flood of rave demos currently swamping the scene.
