The Citadel Project is a solo-developer immersive sim blending Thief-like stealth with survival-horror elements. Set in a medieval megastructure called the Citadel, you play as a prisoner escaping a cell to uncover what an evil force has done to humanity's last line of defense against the Great Storm.
The game emphasizes atmospheric darkness and shadow work designed for hiding. Your primary tool is a crossbow with multiple bolt types. Fire bolts ignite targets. Rope bolts enable climbing and swinging. Decoy bolts create noise for distraction. Moss bolts appear to muffle footsteps for stealth. Enemies are infected with parasites that factor into combat tactics.
A demo is available now on Steam. The Citadel Project enters early access on November 11th.
