For those of you who are interested in seeing what this different version of Necromunda might hold for you before you buy it, imgur user Aracersxx has posted four scans. It appears to be a rather simplified rules set like Age of Sigmar. The one downside I see so far is that (in these few pages) they only have Ork and Marine type weapons, excluding any of the other races GW said will be playable. In other words, expect another book for Shadow Wars in the near future.
As has been discussed amongst my local gamer group, pay attention to these rules as they could be the precursor to what 8th edition 40k holds in store for us.
