About Smash Up: Awesome Level 9000, from BoardGameGeek:

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.
