About Castle Doombad Classic
Castle Doombad Classic is a strategy and tower defense puzzler in which you play the villain, protecting your evil lair from invading heroes. This edition rebuilds and remasters the original 2014 game and adds new content and features.
Defend your lair
You can use over 30 traps and minions to take down the heroes. Combine weapons that fire automatically with traps you activate yourself, timing each one to strike effectively. Unlock and upgrade your traps, troops and castle as you progress.
Game modes
The main campaign spans 90 puzzling stages. You can also play Dr. Lord Evilstein's Roguevenge, a replayable roguelite mode where each attempt differs. As you advance, choose how your castle expands, add traps to your arsenal and collect Nightmare powers.
Customize your villain
Collect loot from fallen heroes to customize the Dark Lord and his control room. Each equipment item provides a Baddie Bonus upgrade, but equipment slots are limited, so you can experiment with different builds. The game also includes cosmetics and reskins for traps and troops.
Key features
- 90 campaign stages and the Roguevenge mode
- Over 30 traps and more than 150 upgrades
