Castle Doombad: Defend Your Lair, Now Free on Android!

The iconic Castle Doombad is back with a vengeance, now available on Android as Castle Doombad: Free To Slay. Brought to you by Grumpyface Studios and published by Yodo1 on mobile platforms, this tower defense strategy game first hit the scene back in 2014. Grumpyface Studios, known for their successful titles like Steven Universe: Attack the Light, Unleash the Light, and Teeny Titans, initially planned a remake of Castle Doombad. They've since decided to split the project into two distinct versions: Free To Slay for mobile and Classic for PC and console.

Castle Doombad Classic, a remastered version of the original 2014 game with updated content and features, is set to launch on Nintendo Switch and Steam later this year. And for fans eager for more, a sequel, Castle Doombad 2: Muahaha!, is currently in development.

Unleash your inner villain, cackle with glee, and wreak havoc as you construct the ultimate evil lair while thwarting those pesky, virtuous heroes. In this game, traps and minions become your arsenal of choice, flipping the typical gameplay on its head.

Castle Doombad: Free To Slay is free to play, supported by ads and optional in-app purchases. Dive into the full original experience featuring 70 stages, daily challenges, and endless modes. Unlock and upgrade over 30 traps and collect more than 100 items to enhance your evil empire.

Enhance your lair's aesthetic with the 'spoils' system, an unlockable cosmetics feature where you can adorn your Dark Lord and control room with various sinister artifacts and loot. Combine these with your personal 'Baddie Bonus' perks for a truly customized experience.

For an added challenge, explore the new rougelite mode, 'Dr. Lord Evilstein’s Roguevenge.' Here, you'll defend against heroes in randomly-generated castle layouts and collect Nightmares, granting you a range of villainous powers and abilities. Ready to embrace your dark side?
