The game has begun! Can the Turtles stand up to the onslaught, or will the Rat King take the early lead?

As the Rat King and his new Trio of Terror—Madame Null, General Krang, and Baxter Stockman—unleash the Armageddon Game on the denizens of New York City and Mutant Town, the TMNT—under the leadership of the newly reformed Shredder—turn to allies old and new to help them in their desperate quest to stop the Rat King’s nefarious plot. Karai, Casey Jones, April O’Neil, Nobody, Alopex, Bludgeon, and Venus—each play an important part in the apocalyptic contest for the world. But can this coalition withstand the Rat King’s latest gambit…or will a new and unexpected alliance form in its wake?  

Collecting issues #1–6 by Erik Burnham, Roi Mercado, Will Robson, Juni Ba, Sophie Campbell, Paul Allor, and Pablo Verdugo, Teenage Mutant Ninja Turtles: The Armageddon Game—The Alliance breaks all the rules!
