Inspired by classic fantasy games, this upcoming stealth adventure takes players through a sprawling medieval fortress filled with undead guards, deadly traps, and hidden dangers.

Stealth fans have a new medieval adventure to look forward to. The Citadel Project, an upcoming first-person game inspired by Thief: The Dark Project and Dark Messiah of Might and Magic, is preparing to launch into Steam Early Access on November 11.

Developed by solo studio Reliquary Software, the game combines classic stealth mechanics, physics-based interactions, and the atmospheric appeal of enormous medieval structures. Players take on the role of a prisoner armed with a sickle, attempting to escape a sprawling fortress patrolled by terrifying undead guards.

The influence of Thief is immediately noticeable throughout the experience. Dark environments encourage players to stay hidden, carefully observe enemy movements, and use shadows to their advantage. A crossbow also provides different tactical options, with specialized ammunition such as water bolts and moss quarrels helping players navigate dangerous situations.

Meanwhile, Dark Messiah inspires the game's physics-driven interactions. Sneaking past enemies is not the only option, as players can shove unsuspecting guards from behind, sending them tumbling off ledges or straight into strategically placed spike traps.

This combination gives players opportunities to approach encounters creatively rather than relying entirely on direct combat.

A playable demo is already available, offering a glimpse into the adventure through a network of underground caverns following the protagonist's escape from imprisonment.

The experience delivers a suitably gloomy atmosphere, with environments that emphasize the impressive scale of the fortress. Its stealth mechanics are relatively straightforward, although some interactions between players and enemies could benefit from additional refinement.

There are also hints of Dark Souls in its progression and storytelling. Bonfire-inspired checkpoints allow players to upgrade their characters, while important story details are revealed through collectible notes and item descriptions.

Although combat features a parry system, The Citadel Project remains firmly focused on stealth rather than challenging action-RPG encounters.

The Citadel Project brings together several appealing elements from beloved fantasy games, offering a combination of atmospheric exploration, sneaking, and environmental combat.

Its early demo already establishes an interesting foundation, particularly through its moody environments and creative physics interactions. While some mechanics still need polishing, the overall concept could appeal to players who enjoy methodical stealth and immersive medieval settings.

The game launches into Steam Early Access on November 11, giving players an opportunity to explore its full experience as development continues.
