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.

Engage in close-quarters combat using pistols, shotguns, and improvised weapons. Every bullet counts in this low-ammo, high-stakes horror shooter.
Gritty, low-poly environments and lo-fi textures create an authentic late-90s horror atmosphere.
Unlock new paths, hidden areas, and escape routes using clues and surveillance guidance from a mysterious ally.
Traverse through themed areas like the cellblock, solitary confinement, infirmary, shower rooms, and guard stations—each with unique threats and layouts.
As you push deeper into the prison, enemies grow stronger, resources become scarcer, and new challenges emerge.
