From the people who brought you Robot Unicorn Attack 2 and Giant Boulder of Death — the monsters are back, and they're dealing out destruction! Pick your favorite kaiju, assemble a deck of special cards and time your attacks to destroy the city. Battle rival players from around the world to decide who's king of the monsters. Unlockable monsters, rare prizes, leaderboards, tournaments and more make this the card game to topple them all!


Unlock and play as giant, crazy monsters. Each have their own specialized MegaZone attacks, elemental buffs, critical hit chance stats, and bonuses. Earn enough tokens winning matches and you’ll be able to unlock them all. Feed them your unused/unwanted cards to level them up fast and make them even more powerful.


Each side is dealt three cards (from their deck of 12) and takes turns attacking until just one is left standing. Damage is based on card power, element (blue, red, green, yellow), and your timing on the boost minigame. Each attack builds your monster’s MegaZone meter; when it’s full you can forego the cards and unleash a mega-powered attack that’ll wipe the smile right off that city’s face.


Pummel opposing cities to increase your metropolis’ population and position in the weekly tournament leaderboards. Even if you lose or are attacked, you’ll gain valuable experience and a couple of precious tokens too. And if you win, you’ll get even MORE experience points and currency. Five leagues (Plushy, Mascot, Monster, Elite and Boss) await!


Four ferocious monsters, over 100 attack cards (with more coming in future updates). Build your City (defense) and Monster (offense) decks any way you like!


When your monster attacks you’ll be prompted to tap the screen at just the right time to boost your card’s stats even higher for a more devastating hit! (And yes there is an option for the slow-reflexed to turn that off.)

Editors’ Notes

After devouring housing complexes in Monsters Ate My Condo!, Adult Swim’s famous antiheroes return—this time in a hilarious card battler. You’ll crack up as you unlock monsters like Boat Head, a giant crab with—you guessed it—a boat on his head, while unleashing powers like Extra Purrestrials (feline aliens, of course). The whole thing’s too ridiculous for words, but timing events keep each battle challenging, while fantastic animations bring monsters to life.



This game is epic! No load times. Action packed. Love the animations. Ive been playing nonstop since i got it. Been able to stay #1 in my league. Some things that could improve the game would be more bonuses or XP points for, example, winning a battle in one hit. Also, it shouldnt be such a tight limit on energy points to play the game. 5 games, then you have to sit out, unless you happen to level up. Lower the amount of energy needed for each play! Also, for pay-to-play, 2.99 for ONE reload of energy is a bit much. You should also let energy build up past 100. Also, buying packs... theres silver packs and diamond packs.. what about gold packs? There should be a inbetween silver and diamond. Also more incentive to play everyday, besides holding rank, you should get small bonus prizes for logging in for X amount of
Consecutive days, or something like that. Great game though!


I play it a lot.

First and foremost, it's a lot of fun to play, and really, that's what matters. Truthfully, I have no prior experience with card based fight games. I was originally taken back by the fact that other than the characters, it was an entirely different animal from its predecessor. But upon giving it a chance, I've been pleasantly surprised. The combination of strategy a luck does make it an entirely new game every time. This isn't to say that the back and forth nature leaves nothing to be desired. When on "defense," all you can do is await the inevitable. And while "hand skills" can at times offset that, there should be some other way to guard yourself or potentially soften the blow.

The addition of the Card of the Day is a welcome one.

The major flaw is the always inexcusable "punish per play" aspect. What's worse is that you lose the same amount of "energy" whether you win or lose a battle. It does, however, replenish rather quickly.

Another problem is that in order to remain in the top tiers, you have to play constantly, which makes it feel like a chore at times.

There are areas where they could improve game play. There should be some level of defense when you opponent plays a card. Also, it's somewhat unfair that the "shield" skill can be nullified via the "color clash," but the "drain thief" skill is not.
