About Castle Doombad Classic
BAD IS BACK! Castle Doombad is the treacherous strategy / Tower Defense puzzler where you play the villain and must defend against the pesky heroes so-rudely invading your evil lair.
This Classic edition includes the original Castle Doombad from 2014, newly rebuilt and remastered from the ground up, plus the addition of brand-new content and features.
IT'S GOOD TO BE BAD!
Slay the good guys with your choice of over two dozen delightfully devious traps and minions! Strategically mix-n-match your arsenal with wicked weapons that fire automatically and manually-activated traps that require precision timing to pack a painful punch! Unlock and upgrade your traps, troops, and castle on your quest to become the baddest of them all!
TWO WAYS TO SLAY!
Break Bad and defend your dark domain across 75 puzzling stages, or take on the nefarious new roguelite mode: Dr. Lord Evilstein's Roguevenge!
In this new mode, the challenge is ramped up, and no two attempts are the same. Choose how your castle expands as you advance, grow your trap arsenal during each run, and collect mighty Nightmare powers to make the heroes pray for a quick Game Over...
SINISTER STYLE!
Collect loot from fallen heroes to deck out your Dark Lord and his control room! Each item includes a Baddie Bonus upgrade -- but your equipment spots are limited, so prepare to tinker with different diabolical builds.
FIENDISH FEATURES:
Includes the original Castle Doombad from 2014 remastered and rebuilt from the ground up -- with no ads and no IAP!
Play the original 75 puzzling stages, or try your evil hand at the challenging new replayable roguelite mode!
Unlock an antagonistic arsenal of 29 traps and over 150 upgrades!
Customize your Dark Lord and your control room with new equipment and cosmetics, or collect reskins for your traps and troops
For the first time, play the original Castle Doombad with a mouse+keyboard!
Play on Steam Deck with touch screen controls (button and joystick support coming soon)
Earn sinister Steam Achievements!
New villainous content coming with free future updates!

Worked out from 111 daily records of the Steam Key for Castle Doombad Classic across 2 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Which Castle Doombad Classic format should you buy?
The cheapest offer is already a key for your own account: €0.37 (€0.75 with fees) at Kinguin, so there is no reason to weigh up a shared account here.
The 1 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Can you activate Castle Doombad Classic in US?
All 7 offers are Global, so the code redeems on any account no matter where it was created.
Why is there such an expensive Castle Doombad Classic offer?
One listing is worth ignoring: the Steam gift that K4G has at €9.63 (€10.85 with fees) is more than 14 times the cheapest offer and is not what this game costs. The number to work from is €0.37 (€0.75 with fees) at Kinguin.
