The game was divided into two parts. The first part was largely inspired by Dungeon Keeper, with players designing their own castle and filling it with traps and minions. Players could upgrade their Castle Heart to increase the size of their castle, as well as how many traps and minions it could hold. Once the player was done, they needed to "validate" their castle, by running through it by themselves and setting a record time.
The second part of the game consisted of raiding the other players' castles. In this mode, the game played much like an action RPG. The Player's goal was to reach the end of the castle and the Castle Heart before the time set by the owner of castle in the validation mode. Failure to reach the end of the castle means that the player couldn't loot the resources of the owner, but could keep the resources and items found during the run.
The game had three currencies: Gold and Lifeforce, which could be either mined or looted from other players, as well as Gems, which were premium currency. The game also had four playable characters: The Knight, The Archer, The Wizard and The Runaway, with The Runaway being restricted to paying customers. Free players could choose only one character, but for Gems, players could unlock additional character slots.
The game's servers shut down October 25, 2016, just over a year-and-a-half after its full release and it is no longer available.
This game contained examples of:
- The Ace: Sir Edrick Painhammer... sort of.
- Applied Phlebotinum: Life force, used to build facilities and rooms.
- Card-Carrying Villain: The Earl of Evilosity.
- Class and Level System
- Familiar: The game's resident thief class was accompanied by a bird.
- Fighter, Mage, Thief: The three original classes fit this.
- Genre Shift: On the offensive? It was an Action RPG. Getting attacked by another player? It was a Tower Defense game.
- Impossible Thief: No matter how foolproof your defensive strategy may have been, there was always going to be someone who slipped through and delivered a hit to your gold and life force supply.
- Mad Scientist: The Earl of Evilosity.
- Mundane Made Awesome: The plot revolved around a fantasy world falling into conflict as a result of an escalated real-estate crisis.
- Mean Character, Nice Actor: "Nice Actor" would be a bit of a stretch, but whenever he was out-of-character, the Earl of Evilosity, as seen in the bloopers, was a bumbling man who, near the end, walked on the set, interrupting Painhammer's filming session; and tapped the camera lens with a clearly confused look.
- Ominous Floating Castle: EVERYONE'S castles, thanks to the castle hearts.
- 100% Completion: Necessary for validation: You had to raid your castle's mines and kill all of its monsters. Any monsters you circumvented will be asleep when a real attacker came knocking. However, the attacker needed only to get to your heart, though destroying mines and killing monsters yielded some treasure. Any castle with multiple paths was thus penalized since the attacker could evade monsters and save time while the validating defender couldn't.
- Power Crystal: The castle heart.
- Shout-Out: Creature names were almost always some kind of reference.
- The Smurfette Principle: The Runaway.
- Spread Shot: Certain crossbows could do this.
- Token Evil Teammate: The Earl of Evilosity again.
- Timed Mission: Attacking players only had a certain amount of time before their end-of-level star rating decreased, and eventually, the door to the treasure room locked.
- Trap Master: Any player that had a good defensive strategy against other players.
- Unwinnable by Design: Technically averted. You couldn't make your castle's defenses too hard because you needed to validate them by running through them yourself, showing that it was possible to beat them. That didn't mean you couldn't employ some severe Guide Dang It! moments where only a specific class with a specific skill load-out and prior knowledge of where the traps and monsters are had a realistic chance of beating the castle.
