I run a local gaming community and we're looking for new and interesting ways to play 40k. I seem to remember a really awesome ruleset put together somewhere (white dwarf? chapter approved? I cant remember....) for 40k Racing. It consisted of several people putting down vehicles or bikes from different races and zooming around a track....while shooting at each other of course.
Does anyone have any information on this? Do these rules exist? or is this just something that Im mistaking for something else? Any help would be greatly appreciated!
