Que Smash Up, era un juego expandible, ya se veía por la temática y se confirmaba, viendo la caja básica en la que existen la mitad de los separadores de facciones libres.
En todo caso, AEG anuncia para marzo del 2013, esta primera expansión que nos ofrecerá 4 nuevas facciones, Fantasmas, Plantas Carnivoras, Steampunks y Caballería de Osos ???. Realmente estos tipos alucinan.

Smash Up: Awesome Level 9000

The Smash Up: Awesome Level 9000 expansion features 4 all-new distinct factions that you can mix and match to defeat your opponents. Try them with the Core Set to create exponential new combinations!

Killer Plants – Better deal with these guy fast, leave them alone and they’ll grow all over the place… like weeds! *rimshot*

Ghosts – Unlike just about every card game in history, Ghosts benefit from having less cards in your hand. Can you be immaterial?

Steampunks – Can’t leave a good base alone, the Steampunks will add new abilities to bases to help your strategies.

Bear Cavalry – What’s scary? A bear. What’s really scary? A cossack riding a bear! Bear Cavalry will use fear to drive opposing minions away to other bases.

Combine these groups into teams of two for various effects! Smash Up: Awesome Level 9000 also contains 8 new Base cards to compete over.
