Castle Doombad: Slay Heroes, Rule Lair

Become the ultimate villain in Castle Doombad: Free to Slay, now available on iOS and Android! Grumpyface Studios invites you to defend your fortress against heroic invaders and embrace a life of wicked fun.

This game flips the script – you're the bad guy, Dr. Lord Evilstein, tasked with protecting your evil lair from pesky do-gooders. Across 70+ campaign levels, deploy over 30 unique traps to thwart knights in shining armor. Upgrade your defenses and ensure your villainous reign remains undisturbed.

Customize your evil lair with "spoils" – wicked artifacts and ill-gotten gains – to create the perfect villain's den. For a fresh challenge, try the roguelite mode, "Dr. Lord Evilstein's Roguevenge," featuring randomly generated levels and endless waves of heroes.
