Glimmer Rats is a comic strip by Gordon Rennie and Mark Harrison. The first episode appeared in 2000 AD prog 2000 (published December 1999), and the story was continued in progs 1174 to 1182. Pictured is the cover Harrison created for prog 1177.
Rennie recalls how "The strip certainly divided people — some loved it, some utterly loathed it. That's better than general indifference, I suppose" (Thrill-Power Overload by David Bishop). A letter in prog 1194 (published in the year 2000) from fan James Leighton said that "Glimmer Rats had by far the most impressive work I have seen since I started buying 2000 AD in '95. The art definitely helped bring out the dark plot, and really pulled you into the story. I hope Glimmer Rats returns within the year." Sadly for James, it didn't, although there is a trade paperback available (ISBN 1904265006).
