Beyond Citadel

The Citadel, humanity’s last stronghold against the Apocalypse, has fallen. Humankind is under the iron grip of the Trumpeters of the Apocalypse. In this dark era, the Martyr—the final safeguard of the Seven Angels—answers a mysterious signal and embarks on a mission to overthrow the Trumpeters and uncover the truth buried beneath the ruined fortress.

Beyond Citadel is a single‑player first‑person shooter inspired by the FPS classics of the 1990s. It blends retro roots with anime‑style 2.5D graphics and tight, realistic gunplay that rewards skill and precision.

• Strategic allies: you are not alone—companions will aid you on your journey through the perilous world.
• Atmospheric world: destructive effects illuminate a dark, futuristic landscape with a distinctive stylistic flair.
