Undead Sentence (AppID: 3850890)

You were never meant to leave this place alive.

Undead Sentence is a retro-style first-person survival horror shooter set inside a quarantined maximum-security prison, now overrun by the undead. You play as Derrick Voss, an inmate who wakes to chaos and must fight to survive while uncovering the truth behind a horrific outbreak.

Inspired by the gritty visuals and atmosphere of PSX-era games, Undead Sentence blends tense exploration, brutal combat, and environmental storytelling. Fight your way through abandoned cell blocks, medical wings, security hubs, and hidden labs, scavenging weapons, ammo, and health supplies as you go.

Survival-Focused FPS Combat

Engage in close-quarters combat using pistols, shotguns, and improvised weapons. Every bullet counts in this low-ammo, high-stakes horror shooter.

Retro PSX-Inspired Visuals

Gritty, low-poly environments and lo-fi textures create an authentic late-90s horror atmosphere.

Environmental Puzzles & Exploration

Unlock new paths, hidden areas, and escape routes using clues and surveillance guidance from a mysterious ally.

Multiple Zones

Traverse through themed areas like the cellblock, solitary confinement, infirmary, shower rooms, and guard stations—each with unique threats and layouts.

Progressive Challenge

As you push deeper into the prison, enemies grow stronger, resources become scarcer, and new challenges emerge.

Will you uncover the truth… or join the undead?
