It's an original card game Simon designed to support our CKC Trading Cards, which simulates a brawl between kaiju. It makes heavy use of the terms & concepts (and color-associations!) we've established for Colossal Kaiju Combat, such as:
As of 2015, we VERY MUCH suggest you buy the new trading card CCG (SPN4 and future sets) rather than the Combat Deck. We no longer support the Combat Deck - future characters and abilities are designed to support the new CCG instead.
These are printed on-demand through The Game Crafter Original Combat Deck, Combat Deck v2. Being print on-demand is really awesome - because it means that Sunstone Games doesn't have to spend a bunch of money up-front to manufacture & warehouse the cards - you order one, they print it and ship it to you direct!
Both versions of the Combat Deck allows you to fight Trading Card kaiju against one another - buying some Trading Cards gives you a lot of characters to choose from!
NO! The Combat Deck is a complete game by itself. Each version contains 4 characters you can use - 6 different matchups! But each pack of Trading Cards gives you 8 additional characters - increasing that number to 66!
Version 1 is a straight-up brawl between 2 kaiju. 3 turns of 3 rounds each, then you compare life totals to decide a winner. Version 2 is a team-based game, where each player controls 2+ kaiju, and there is a neutral building on the board which may be attacked for victory as well. Those games are much more dynamic, but can run 15-20 minutes each. Version 2 also supports 3 or 4 players, if you shuffle 2 decks together!
