Source facts
What is the primary objective when playing Castle Doombad?
Your main objective is to act as the Big Boss Bad Guy by constructing various traps and defenses within your sinister lair to successfully thwart the waves of heroes attempting to infiltrate your castle throughout the game's ninety stages.
How should I approach the combat mechanics during a stage?
You should focus on strategically combining automatic weapons with precision-timed manual traps. This approach allows you to trigger maximum chaos against the incoming heroes, helping you manage the onslaught more effectively as you progress through the different castle themes.
What is the difference between the standard stages and the new mode?
While the game features ninety puzzling stages across six distinct castle themes, you can also choose to play the challenging new replayable roguelite mode, which offers a different way to experience the tower defense gameplay compared to the standard campaign.
