Thief: The Dark Project Remastered launches December 3 on consoles and PC, and the 1998 original isn’t the only thing in the box. Nightdive Studios, Eidos-Montréal and Atari announced on November 2 that the $29.99 release also includes The Tarnished Mirror, a brand-new official campaign made by the modders behind The Black Parade. Garrett is back in the shadows, and this time the modding scene came with him.

Four New Missions From the Black Parade Team
The press release calls it a rare industry moment, and it’s hard to argue. The Tarnished Mirror comes from the creators of Thief: The Black Parade, one of the most ambitious fan expansions PC gaming has seen, and Nightdive and Eidos-Montréal are bringing it into official canon.
The Steam listing pegs it at four missions, set after the events of The Dark Project and built as a bridge to Thief II: The Metal Age. A simple theft spirals into imprisonment, shaky alliances and a drowned, R’lyeh-like necropolis, with new factions, a bigger enemy roster and the Lovecraftian streak Thief fans will recognize. It’s included with the game, not sold separately.
Nightdive also confirms the remaster runs player-made mods, The Black Parade included.
19 Missions, Gyro Aim and Up to 4K at 120fps
Nightdive rebuilt the game in its KEX Engine, the same tech behind its Quake II, Turok and Star Wars: Dark Forces remasters. By the store page’s count, you get:
- The 12 original Thief: The Dark Project missions
- The 3 Thief Gold missions from 1999, which add five new enemy types
- The 4 Tarnished Mirror missions
- Up to 4K at 120fps
- A weapon and item wheel, rumble, and motion/gyro controls on gamepads
- A mission selector to replay anything you’ve finished
- A Vault of behind-the-scenes material
- Touched-up textures, models and animations, plus small fixes to the original level design
Each mission still has three difficulty settings with different objectives, and the light-and-sound stealth that made Thief a “first-person sneaker” in 1998 is the core of it. Knock guards out with the blackjack, douse torches with water arrows, and save the sword for when it all goes wrong.
$29.99 Digital, $69.99 for the Trapezoid Big Box
Five editions, all with the same game and The Tarnished Mirror inside:
- Standard Digital, $29.99. PC and consoles.
- Digital Deluxe, $34.99. Adds an art book, the official soundtrack and an excerpt from an upcoming Thief: The Dark Project novelization. Steam and GOG list it at $34.97.
- Standard Physical, $29.99. PS5 and Switch 2.
- Steelbook Edition, $39.99. The game, a Steelbook and a printed manual.
- Deluxe Trapezoid Edition, $69.99. The game, a printed manual, a Steelbook and a Remaster Diary, packed in a recreation of the trapezoid-shaped big box the original came in.
Physical pre-orders are open now through Atari. The digital Standard is already up for pre-order at $29.99 on GOG, Steam and Xbox.
Free Switch 2 Upgrade, and Carts That Run on Switch
Switch owners don’t have to pick. The Switch version upgrades to the Switch 2 Edition for free, and every Switch 2 physical edition also plays on the original Switch. Want the trapezoid box but haven’t upgraded yet? It still works in your old console.
GOG First on PC, and Mods Stay PC-Only
Thief is on GOG day one, DRM-free, and that’s exactly where an old Looking Glass game belongs. If you want a copy you play and own outright, GOG has it at $29.99. It’s also on Steam and the Epic Games Store at launch. On Xbox, it’s a Play Anywhere title, so one purchase covers Series X|S and Windows.
Atari’s page marks custom campaign support as PC only. If you want to play The Black Parade on the new engine, that’s a PC job.
A 2.0 GHz Dual-Core and 2 GB of RAM
The bar is about as low as a 2026 release gets. Nightdive’s specs on Steam are Windows only, and both tiers ask for the same graphics support:
| Minimum | Recommended | |
|---|---|---|
| OS | Windows 10 (64-bit required) | Windows 10 (64-bit required) |
| Processor | Intel or AMD Dual-Core at 2.0 GHz | Intel Core i5-2300 2.8 GHz / AMD Phenom II X4 945 3.0 GHz or equivalent |
| Memory | 2 GB RAM | 4 GB RAM |
| Graphics | GPU with DirectX 11 or Vulkan 1.1 support | GPU with DirectX 11 or Vulkan 1.1 support |
| Storage | 5 GB available space | 5 GB available space |
| Sound | 100% DirectX compatible sound card or onboard sound | 100% DirectX compatible sound card or onboard sound |
GOG lists the same hardware but asks for 8 GB of storage, so clear 8 GB if you’re grabbing the DRM-free build. On console, it’s PS5, PS4, Xbox Series X|S, Switch 2 and Switch.
Thief: The Dark Project Remastered is out December 3. Nightdive hasn’t posted an unlock time yet, and we’ll add it when it does. Keep to the shadows until then.
