Featuring four new factions and eight new bases, Smash Up: Awesome Level 9000 – a.k.a. Smash Up II – integrates into the Smash Up base game, bringing exponential new combinations of factions and playstyles! Smash Up: Awesome Level 9000 includes:
Killer Plants – Better deal with these guys fast because if you leave them alone, they'll grow all over the place...like weeds! *rimshot*
Ghosts – Unlike in just about every card game in history, Ghosts benefit from having fewer 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 to other bases.
