Idle Big Devil

From the Devs

Humans, Demons, Elves and Undead coexist peacefully on the same continent until the balance was broken: A fallen prince of the human kingdom accepted the contract with Undead, and evil spirits arose from the hell to cloud the minds of most creatures.
In such a critical situation, you are appointed by the King as a new lord with the duty to gather new heroes to fight against the darkness.
One of the elders secretly tell you a secret that the energy of heroes can be combined.
And the High Priest creates a device to duplicate heroes. All duplicates have no feelings or minds.
With all these, you are going to prepare yourself for monsters, fallen heroes, and other competitive lords.


The aim of the game is to collect and assemble a group of Heroes and to continuously improve and equip them with new items. Progress in the campaign mode, tower of infinity and many other modes to be rewarded with powerful Artifacts, Equipment or Set Items.

• An IDLE game with 3D graphics.
