It’s fundamentally the same as 7th edition but with a few tweaks and some clarifications on certain rules.
I would think you could get by with the 7th edition rule book, but if you’re playing regularly then I’d recommend getting the new version.
Don’t worry about committing to a campaign, we’re just trying to get more people involved by doing multiplayer ZM games and 2v2 games, we’re trying to focus more on the narrative side of things, encouraging ‘fluffy’, thematic armies to put more emphasis on the setting and having fun
it’d be great if you want to have some games with us. Which legions do you have?
at the moment we have:
Alpha Legion (T)
Iron Hands (L)
Iron Warriors (x2!)
Sons of Horus (T)
Dark Angels (L)
Raven Guard (L)
I’m not 100% on the allegiance of our Iron Warriors and Solar Aux, plus I think there are some more armies I have probably forgotten
