r/falloutfactions

I’m genuinely really confused with this game. I’m coming from 40K and Age of sigmar where rules feel really straight forward and easy to get, i understand factions is a newer game but this feels impossible and super confusing. It’s my belief that if I just want to play a 1v1 with a friend I am to play this c.o.m.p game mode correct? I don’t want to do anything lasting that carry’s over like campaign I believe but for c.o.m.p I see there are different rules. In the crew folio which I’m assuming is where I get my rules for my minis from it shows some factions as having rules to be used for campaign only, what if I want to play these in comp, is there somewhere else I go? Can I even use them in comp? Is there a way to make it work, like what if I want to play the Zetan, can I just ignore the campaign tag and still use them in a casual game.

I’m not sure maybe I’m misunderstanding everything. Can someone guide me here I just want to collect the correct miniatures that I can actually use and play in a casual 1v1 game.
