Which digital format of Castle Doombad Classic should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

If I buy the account format of Castle Doombad Classic, will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Why is the Steam Key of Castle Doombad Classic safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Castle Doombad Classic to your game library. The account format requires more complicated steps and is more prone to errors during activation.

What issues can arise when activating a Steam Key of Castle Doombad Classic?

How long will I have to wait to receive the Steam Key of Castle Doombad Classic after purchasing it from a store?

Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.

What guarantee do I have that the listed stores are reliable?

At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.

The store does not send my order and does not respond to support. What can I do?

Don't worry, we have the solution. We will handle it ourselves.

The final price is higher than indicated.

Many stores add payment fees, taxes,... in the cart. So be prepared to spend a little more.

I'm desperate: They don't send me the game, the store ignores me. I think I've lost my money.

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!
