Smash Up is a card game that takes a deck of 20 cards of a faction, and combines them with another deck of 20 cards of another faction. Each faction has a special ability associated with it, so the combinations when mixing various factions is almost endless. These cards are shuffled to make your deck, and you use that deck to attempt to Smash a base. Points are awarded for the first, second, and third most power on that base.
Smash Up on Steam is currently in what Steam calls an ‘Early Access Game’. This grants you early access to the full game in its current state allowing you to play as is, with more content added as the developer completes it. If you buy into the game during Early Access, you’ll receive a discount as well as access to additional content as it’s completed.
