The Citadel Project is a Thief-inspired dark fantasy, survival-horror lite stealth-em-up with some lovely shadows set in a medieval megastructure
The Citadel Project is an upcoming immersive sim that blends Thief-like stealth gameplay with survival-horror elements, created by a single developer. Set in a dark fantasy world plagued by parasitic corruption, the game takes place within the Citadel—a massive medieval megastructure built by the Ancient Kings as humanity’s last line of defense against an apocalyptic threat known as the Great Storm.
The game emphasizes stealth mechanics characteristic of immersive simulations, allowing players to navigate the Citadel quietly rather than through direct confrontation. What sets it apart from typical stealth games is its incorporation of horror elements, creating an atmosphere of dread as players explore the corrupted structure. This combination of stealth and survival-horror is relatively uncommon in immersive sim design, with Gloomwood being one of the few recent examples.
The Citadel itself serves as both setting and narrative device—not merely a location but a structure under siege, with an evil force actively corrupting it from within. This setup creates tension between the player’s need to survive within the Citadel and the structure itself being compromised. The parasite-infected world and dark fantasy aesthetic contribute to the game’s oppressive tone.
The project’s single-developer status is notable within indie gaming, suggesting an ambitious vision realized by a dedicated creator. The emphasis on atmospheric design—particularly the “lovely shadows” highlighted in the game’s description—indicates careful attention to visual storytelling and the use of lighting as both a gameplay and narrative tool.
The Citadel Project represents an intersection of immersive sim design with survival-horror atmosphere, targeting players who enjoy thoughtful, stealth-focused gameplay within richly atmospheric dark fantasy settings.
