Intergalactic: The Heretic Prophet appears to offer players a significantly greater degree of freedom than the studio's previous titles. Drawing inspiration from Elden Ring, the developers aim to integrate similar open-world exploration mechanics into their latest project. Journalist Ben Hanson disclosed that the game will be set on a vast single planet, where players will unravel the mysteries of a lost civilization and delve into a new religion that plays a central role in the narrative. While it's uncertain how closely the game will align with traditional open-world concepts, it's clear that the developers are steering away from the linear structures seen in their past games.

The Heretic Prophet marks the studio's first venture where players will navigate the game world solo, without companions or allies. Neil Druckmann emphasizes the studio's goal to evoke a sense of isolation within an uncharted universe while exploring profound themes of faith and religion. The story unfolds in an alternate future on the planet Sempiria, isolated from the rest of the galaxy for over 600 years. It is on this planet that bounty hunter Jordan Moon arrives to fulfill her contract.

Druckmann also highlights that the game's development has been influenced by titles such as Half-Life 2 and Monkey Island. This suggests a departure from conventional guidance systems and a move toward a narrative style where players must piece together the story themselves.

Intergalactic: The Heretic Prophet was announced at TGA 2024, though a release date has yet to be confirmed.
