Shown in the debut trailer for Intergalactic: The Heretic Prophet is just the tip of the iceberg, according to Neil Druckmann

Neil Druckmann shared new details about Naughty Dog's upcoming game Intergalactic: The Heretic Prophet. He noted that the previously presented materials are only the 'tip of the iceberg', hinting at the scale of the project.
Here's What We Know
Druckmann said that the game is already in a state suitable for internal testing, and the team is happy with its current look. He expressed his impatience with the public gameplay, emphasising that what was shown earlier is only a small part of what awaits players.
Intergalactic: The Heretic Prophet is the new intellectual property of the creators of Uncharted and The Last of Us. The game is set 2,000 years in the future. The story explores the themes of faith and religion, focusing on the adventures of the protagonist, bounty hunter Jordan A. Mun, played by actress Tati Gabrielle.
The game is being developed for the PlayStation 5, but no release date has been announced. Druckmann admitted that the team still has a lot of work to do and does not yet have a clear idea of the final look of the project.
As a reminder, Jason Schreyer believes that the game will be released only in 2027.
