About This Game

HUNKER BUNKER is a retro-futuristic tactical survival game about leading

a squad through a shifting underground bunker, scavenging salvage, and keeping

the lights on when the dark starts moving back.

You command three specialist operators:

  • Scout for fast recon and wide salvage coverage.

  • Tank for heavy defense and frontline survival.

  • Engineer for rerouting systems, terminal work, and tactical utility.

Every run pushes you deeper into procedural bunker corridors, hostile biomes, and broken infrastructure.

Manage oxygen, recover resources, repair critical systems, and decide which threats are worth fighting when supplies run thin.

Features

  • Procedurally generated bunker runs with shifting layouts and escalating pressure.

  • Distinct operator classes with different movement, abilities, and combat roles.

  • Oxygen and salvage management that rewards careful route planning.

  • Discoverable terminals, lore logs, codex entries, camps, and faction secrets.

  • Multiple endings that reflect the choices and survival of your crew.

  • Keyboard/mouse support, touch-friendly UI, and remappable controls.

Some secrets in Hunker Bunker are not hidden behind keys.

They are hidden behind the cost of surviving long enough to ask the right questions.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Hunker Bunker uses generative AI tools during development to assist in creating some pre-generated visual assets, including select in-game illustrations, collectible artwork, and promotional imagery. These assets are generated before release and are reviewed, edited, and integrated by the development team. Hunker Bunker does not use generative AI to generate content live during gameplay.

Hunker Bunker contains frequent sci-fi violence and horror, including firearm combat, blood and biological splatter, acid injuries, dismemberment, corpse disintegration, parasitic infection, and body transformation. The story also includes psychological horror involving manipulation, loss of bodily autonomy, mind control, captivity, and disturbing biological imagery.

Some story paths address death, self-sacrifice, self-annihilation/suicide themes, and characters facing or anticipating their own deaths. The game also contains occasional non-explicit sexual and sensual themes, suggestive dialogue and intimacy, references to sex work as part of a survival economy, and limited implied/veiled nudity. Sexual activity is not graphically depicted, and the game does not contain explicit sexual acts or explicit genital nudity.
