I start playing again, but what to buy ?

Hello Hunters,
i started playing C.H. again after a few years, having tried it on Steam a long time ago but then abandoned. I would like to buy something but i see that there are separate purchasing sectors (Bundle-Pizza) :

1) Basic Edition, Artifact Bundle, Citadel Bundle, AI Bundle
2) Pizza

I understand what Pizza is for, but what are other Bundle options ? do they offer different content, or does the $19.99 Basic one contain the others as well ?

Thank you.

 

Each bundle unlocks different treasure hunts (premium modules) and figures (character skins). The figures are purely cosmetic, so if you don't want them it's cheaper to unlock treasure hunts with pizza.

 

ok;

with Treasure Hunts do you mean additional Adventures on the map ?

 

Yes, they have a lock symbol on the world map.
