Ash wastes rules were printed in various
Publications such as fanatic magazine. And some
Legend at Yaktribe (where I am but a lowly lurker) uploaded and compiled them in one document.
You still need original Necromunda to play. Think of it as an expansion pack.
In short, yes it’s gorkamorka. The biggest difference is the boosting thing isn’t a thing. I guess even mutants and ash wasters being some of the most unhinged people you’d ever meet still ain’t quite as mad as the average ork! Haha
The missions are nice. Good mix of Necromunda and gorkamorka. Plenty of opportunities to run around multi story death traps in foot missions and plenty of chances to get all mad max (including the classic rolling road scenarios from GoMo)
