On Nov. 5, Kabam, the mobile studio behind Marvel Contest of Champions, revealed WB All-Star Mayhem, an idle RPG for iOS and Android made under license from Warner Bros. Interactive Entertainment. It brings more than 100 characters from nine Warner Bros. animated series into one game, and executive producer Sebastien Goode described it as a love letter to the golden eras of animated TV, built to feel authentic to fans. Limited regional testing starts in select markets later in November.

The details

The nine series are Justice League Unlimited, Adventure Time, Looney Tunes, Teen Titans Go!, Animaniacs, Scooby-Doo, Steven Universe, Samurai Jack and The Powerpuff Girls. Batman, Superman, Bugs Bunny and Finn and Jake are among the launch characters. The story follows the Brain (of Pinky and the Brain), who gets hold of a Universal Remote that opens different TV worlds and teams up with villains from each one.

Kabam plans to add more characters and worlds after launch. According to PocketGamer.biz, Marvel Contest of Champions has earned more than $2 billion on mobile. No wider release date has been announced yet.

🎮 Pro Tip

I love this. Kabam already showed with Contest of Champions that a deep roster of famous characters can keep a mobile game going for years, and Warner Bros. has one of the biggest animation libraries around. Parents who grew up on Cartoon Network can play this one with their kids. No doubt more IP owners will bundle their catalogs this way.

What to watch

Watch the regional test. If players stick around, expect a wider launch and more of the Warner Bros. vault to follow. Let's see which franchise joins first.
