Updated:
Learn about Thief: The Dark Project remastered, including its December 3, 2026 launch, story expansion, KEX Engine upgrades, and system requirements.
Introduction: A Stealth Pioneer Returns
Nightdive Studios is preparing to return players to the shadows with Thief: The Dark Project remastered, a planned re-release of Looking Glass Studios’ genre-defining 1998 stealth game. According to the official Steam store listing, Thief: The Dark Project remastered is scheduled for release on December 3, 2026. The page describes the original as a “first-person sneaker” that pioneered light-and-sound stealth mechanics, letting players hide from or sneak up on characters rather than simply attacking them. The remaster uses Nightdive’s KEX Engine and includes the original game and Thief Gold content.
Key details from the listing:
- Planned launch: December 3, 2026
- Includes Thief Gold missions, content, and updates
- Built on Nightdive’s KEX Engine
- Check the live Steam Deck compatibility label on the official store page before deciding whether to play on Steam Deck.
The official Steam page describes Thief's use of light and sound as central stealth mechanics, allowing players to hide from enemies or approach them without being detected. View the official Steam page.
The Tarnished Mirror Expansion
The official Steam page says Thief: The Dark Project remastered includes a new story expansion called “The Tarnished Mirror.” View the official Steam listing. This expansion is described as an original four-mission campaign set after the events of Thief: The Dark Project, and it comes from the creators of the acclaimed The Black Parade mod. The setup follows Garrett after the Trickster’s defeat: he finds himself shortchanged and back to small-time jobs while The City experiences political and ideological upheaval. A seemingly straightforward theft of a Precursor hand-mirror pulls him into an unthinkable conspiracy.
For players diving into Thief: The Dark Project remastered, this extra campaign expands the core remaster with narrative content beyond the original Gold missions. The following table summarizes the expansion details provided by the store page.
| Expansion detail | Developer-provided information |
|---|---|
| Expansion name | The Tarnished Mirror |
| Campaign length | Four missions |
| Story placement | After the events of Thief: The Dark Project |
| Origin team | Creators of the acclaimed The Black Parade mod |
| Premise | A Precursor hand-mirror theft draws Garrett into an unthinkable conspiracy |
The expansion is included with the remaster; it is distinct from the three additional missions introduced in Thief Gold.
KEX Engine Remaster and Quality-of-Life Changes
Nightdive Studios has rebuilt Thief: The Dark Project remastered on its proprietary KEX Engine.
