This is an expansion and requires the base game to play: yes

Smash Up is back with even more wild factions in the mix! Science Fiction Double Feature brings four new decks to the base-smashing business with abilities unlike those seen before!

• Time Travelers allow you to reuse your cards time and time again
• Cyborg Apes take actions that attach to your minions and take them to a whole new level
• Super Spies use their mojo in espionage to plot out the future of you and your opponents
• Shapeshifters could be anyone!

Smash Up: Science Fiction Double Feature can be played on its own as a two-player game or combined with other Smash Up titles to allow for up to four players to compete at the same time.
