Castle Doombad 2: Muahaha! is the sinister sequel of the 2014 hit Tower Defense puzzler -- making its devious debut with brand new content, a new story, 2-player Co-Op Mode, and an evolution of the classic Castle Doombad gameplay!

YOU are the villain – and life as a baddie sure is good! At least it was, until pesky heroes decided to invade your quaint little lair o’ despair. Turns out they’re not too keen on the whole “captured princess and prince” situation. What’s a Big Boss Bad Guy to do? Decking out your castle with a heinous heap of traps, monsters, and dastardly weapons seems like a good place to start!

Choose from over 35 delightfully devious traps and minions to devise and deploy your own diabolical designs of do-gooder destruction! Strategically place traps on walls, ceilings, and floors to uncover the multitude of wicked ways they can complement and combo off one another. Then add a sinister sprinkle of free-roaming minions and manually-activated traps that require your precision timing to pack a painful punch...

Unlock, upgrade, and customize your traps, troops, and castle on your quest to become the baddest of them all!

Play the entire game either in Single Player or become Co-Villains alongside a friend in 2-Player Co-Op! You and your partner-in-crime must choose different traps and tools, so you'll need to rely on each other and plan your evil schemes accordingly. Available in local play or via Steam Remote Play.

Castle Doombad 2: Muahaha! is currently in development and we'll be revealing more of the sequel's new features (and some big surprises) in the future. Please stay tuned!

From the team that brought you Steven Universe: The Light Trilogy, Teeny Titans, Super Mole Escape, Bring Me Sandwiches!!, and more!
