The thing about Smash Up is that AEG can pull in references from pretty much everywhere in order to make new factions. In this case, they’re hitting the wayback machine to the time of disco, bell bottoms, platform shoes, and polyester leisure suits. Yes, it’s the 70s.
From the post:
Can you dig it? We’ve put Smash Up into the not-so-wayback machine and set the controls for “GROOVY!”
That 70s Expansion celebrates all the greatest pop-culture memories from the Age of Aquarius! Put on your mood rings, bust out your leisure suits, spin that disco ball and put the pedal to the metal good buddy! The streets are mean, there’s a bear in the air, but the music is fantastic and everyone is Kung Fu Fighting!
