I took a look through my old cd's, and gathered together all of the hundreds of SP Blood maps that I could find. I may have missed a few, and I didn't check them all, so there may be a few BB maps mixed in there as well. But this should keep you busy for awhile. Enjoy!
there are alot of cool maps here that arent on Gameleader's page or anywhere else for that matter. I like House, Spooky, and 6 Keys for maps to check out (as far as Ive seen so far).
I've discovered some additional maps on some old cd's. Eventually I'll get around to gathering them all up again, and then creating some permanent place to put them all.
