The game is set in a warped fantasy world where the unicorns are rabid, seven former heroes have become as corrupt as the world-threatening evil that they once fought to destroy, and impish creatures known as minions believe you to be their overlord. In fact, the overlord in question has been dead for ages, but when the minions spot you, a powerful sorcerer, emerging from his castle at the start of the game they decide to pledge their lives to you, effectively giving you the means to destroy the aforementioned fallen heroes and become the new overlord if you wish.

One of the most amusing things that we saw during the demo was the way that the warrior minions ransacked pretty much every location they went to looking for items that they could equip. The result was a ragtag mob of minions sporting varying degrees of makeshift armor and armed with pitchforks and such. One of the minions even managed to find a chef's hat somewhere along the line, which afforded him very little protection but made him easy to spot in the crowd.​

Controlling a mysterious figure that has inherited the legacy of the evil, long-dead Overlord, the player emerges, near death, from the ruins of the old Overlord’s Dark Tower. Only the player’s actions will determine if they will rise to become the new all-powerful Overlord; it’s all down to how much of a bad ass they want to be in order to succeed... evil or really evil! Played out with plenty of black humour and dark irony, the game will immerse players in twisted parodies of classic fantasy scenarios and characters.

Says Lennart Sas, Director at Triumph Studios: "Overlord offers a wealth of freedom and allows players to experience classic fantasy like never before. Working with the minions, players can loot and pillage their way through the game’s world or maybe resist the temptations of evil. In Overlord, player choices truly shape the world."​
