A little more than a month ago, we learned that Cartoon Network was readying a sequel of sorts to their massively popular card battler Card Wars – Adventure Time ($3.99), and earlier today that game, Card Wars Kingdom (Free), went live in the App Store. Just as the first game was adapted from a fictional card game that was played in an episode of Adventure Time, Card Wars Kingdom is loosely based on the latest episode Daddy-Daughter Card Wars where Jake has to win an underground Card Wars tournament. Fittingly, Card Wars Kingdoms has a brand new online PvP feature and tournaments.

In addition to multiplayer stuff, Card Wars Kingdom features a revamped card battle system, a Creature Lab where you can collect and upgrade a stable of creatures, and a new Daily Challenge system, among other things. It seems like a great evolution of the already great original, so if you’re into Adventure Time or card battlers, or you were a fan of the original Card Wars game, you should definitely check out the new Card Wars Kingdom for free and visit the game’s forum thread to share your thoughts about it.
