Castle Doombad: Free to Slay lets you take revenge on pesky heroes invading your evil lair, out now

Become the ultimate villain in Castle Doombad: Free to Slay! Grumpyface Studios' new mobile game, now available on iOS and Android, lets you defend your evil lair from heroic invaders. As the nefarious Dr. Lord Evilstein, you'll strategically deploy over 30 traps across 70+ campaign levels to thwart pesky knights. Upgrade your defenses and customize your villainous hideout with wickedly cool "spoils"—think evil artifacts and pilfered treasures.

For a fresh challenge, dive into the roguelite mode, "Dr. Lord Evilstein's Roguevenge," where randomly generated levels and relentless heroes test your strategic mettle.
