A strategy game developed by Realmforge Studios and published by Kalypso Media in 2011, can be somewhat considered the spiritual heir of Dungeon Keeper.Also had a standalone expansion called "Dungeons: Dark Lord".Like the above mentioned game, you play as an Evil Overlord residing in his dungeon with his goblin minions. You have to build and expand the dungeon by using Gold and Soul Energy which you can harvest by capturing heroes that wander into your dungeon. In order to gain more and more Energy you'll have to keep them satisfied with treasures, good fights, traps and other goods. It also has a single player campaign with a unique gameplay system, where you lead the Dark Lord Deimos in his Roaring Rampage of Revenge against Kalypso, his treacherous ex-girlfriend.Compared to Dungeon Keeper it's much more simplified and focuses more on heroes than your own creatures and takes elements from Theme Park and Tower Defense systems.
An Ice Person: The Expansion add an ice-themed dungeon with ice-related monsters.
Anti-Hero: Basically all the heroes that enter your dungeon will be looking for gold, fame, books and / or weapons and leave once satisfied. They'll only try to destroy you if they're bored or rallied by a champion.
Annoying Arrows: Minos seems nonchalant about the half dozen arrows embedded in his shoulder.
Back from the Dead: If your Dark Lord is killed, he'll be resurrected by the Dungeon's Heart at the cost of some of the Heart's Health. This applies to your enemies aswell in the story mode.
Badass Bookworm: Necromancers. They read a lot of books and scrolls when they're not busy crushing foes around.
Curb-Stomp Battle: You'll spend most of the game hunting down heroes and inflicting them a crushing defeat. However, on higher difficulties and against multiple opponents you may be defeated. Justified as you receive a huge boost in power as long as you're inside your area of influence.
Some heroes like to be on the other end of one to fill their soul energy. At least they have to stay alive long enough to inflict the amount of damage needed to satisfy them.
Human Sacrifice: In Hell, you can sacrifice a hero in order to obtain all his Soul Energy at once. However it will hasten the arrival of the next Champion.
Inexplicable Treasure Chests: You can put them around the Dungeon to satisfy the heroes. They can vary from small chests, large hoards with jars and crates to humongous hills of gold from the depths of Hell itself.
Knight in Shining Armor: Champions will occasionally appear. Unlike other heroes, they're not distracted by treasures or rooms or decorations and they'll slay every monster in their way, free any imprisoned or tortured hero they come across and try to destroy the Heart of the Dungeon. They can also persuade other heroes to join them. Torture and sacrifice can hasten their arrival. Conversely, releasing captured heroes delays them.
Lost Forever: Your Gold, if a hero manages to escape alive after pillaging your vaults. Luckily you can get money from other adventurers.
Malevolent Architecture: You can build traps in order to damage heroes and entertain rogues and assassins (who can get Soul Energy by disarming traps). There are also tons of sinister decorations that you can build in order to make your Dungeon more interesting and raise your Prestige points, which allows you to purchase better decorations and attract stronger heroes.
Marathon Boss: Kalypso, in a way: in order to defeat her you have to: slay two Dark Lords, then reach the next level where you are ambushed by several heroes while Kalypso ran to your dungeon, taking over all your pentagrams. That force you to fight her at your minimal strength. Then, you have to get back to the Throne, fight three waves of monsters and finally take her down for good.
Mercy Rewarded: If you free a prisoner you can delay the next Champion. It's usually a smart move to do after ordering the torture or sacrifice of another prisoner.
Mooks: Your Goblins, who are in charge of the Dungeon and refill treasures and armories, rearm traps, dig new rooms, mine for gold and also carry defeated heroes to prison. If they're slain you can summon more.
Especially the Expansion. The Story is pretty much a spoof of Lord of the Rings. The opening cutscene shows the Dark Lord trying to forge the Other Ring and failing twice, producing... a rubber duck and a toybox.
Sorting Algorithm of Evil: You start with the feared but not-so-strong Zombie King in the catacombs, then the mighty Minotaur Minos in the temple and finally Kalypso, a powerful Succubus, in the pits of hell.
Soul Jar: The Dungeon's Heart, a huge, pulsating gem. You lose if the Heart is destroyed, but luckily you can repair it. The Zombie King has also literal jars that keep healing him if not destroyed.
Spikes of Villainy: You can even use them as part of the decoration to make your Dungeon more interesting.
Wicked Cultured: Minos the Minotaur Lord. His first task involves building 20 library gimmicks, so that monsters won't grow ignorant over time.
You Require More Vespene Gas: Three resources: Gold (from adventurers and mining) is used for buying most of the items you need to outfit your dungeon. Soul Energy (from captured heroes) is used to increase the monster level of the dungeon, summoning the guardian and to build prestige decorations. Prestige (from the previously mentioned decorations) makes your Lord more powerful and unlocks additional items.
Zombie Apocalypse: Guess how the Zombie King tries to chase you away from his dungeon?
