Its been busy the last few days, digging through rumors and bits to find the latest Genestealer Cult information. Now we have some rules as well for city ambushes, along with a link that shows a few more images, and hopefully something new (I think one of the leaked images shows some new pages from White Dwarf) at least to me.

Please give the city ambush rules a little salt on this. They are early, and mistakes are very possible on this.
