Developed by renowned gaming studio Gas Powered Games, Demigod lets players take control of an immensely powerful being whose goal is to defeat his brethren in a series of epic arenas in order to ascend into the pantheon of the gods. During the course of each battle, players gain experience, purchase equipment, learn magical spells, capture key resources and upgrade their Citadel while working to lay waste the opposing faction. Demigod battles take place in spectacular environments that are visually stunning and yet still run well on relatively older hardware thanks to a new technology developed by Gas Powered Games that optimizes the way rendering is executed on most video cards.

In single player, Demigod provides both a skirmish mode for individual battles as well as a tournament in which players choose a Demigod and compete against other Demigods controlled by the computer to gain the most favor points with the gods in order to ascend. In multiplayer, players can compete in online skirmishes in which matches players together based on their skill and experience or participate in the Pantheon, a persistent online tournament in which players choose a faction and earn favor points to through victory in the arena. Wins, losses, experience and much more is available.
