It only has tutorials for singleplayer at the moment with plenty to come it says, and it looks like you spend game tokens to buy extra miniatures and cards etc.. this would normally put me off BUT its really good fun and I would break my own rules and buy addos for it.
I just played a multiplasyer game, and it was great fun, the die rolls are great, throwing a card in a battle is good, its turn-based even in multiplay which is why its good for me.
the game is quality through and through, but only multiplayer is available now, and you will be buying addons, but I put up a good fight with bad miniatures against a guy who had buffed his up, so I believe its doable,
when you do a raned attack the obsticles reduce your dice pool, that's good
