GET YOUR BEARINGS
About Human Host
In a world ravaged by an airborne zombie virus with years‑long incubation, you are one of the few born immune. Survival hinges on clever use of physics, construction, and combat in a relentless, procedurally generated landscape. The game blends realistic collision feedback, fully destructible terrain, and a sandbox vehicle system, letting you craft mobile fortresses from any material. With diverse firearms, traps, and oppressive bosses, each night brings fast‑moving hordes that test your ingenuity. Single‑player mode is supported on Windows, with Steam Workshop integration for community creations.
01 / THE GUIDE
Realistic Physics & Armor
Collisions deliver outstanding hit feedback, and armor physically covers the body surface instead of using abstract defense numbers. This means damage is blocked by the actual shape of the armor you wear, creating a tangible sense of protection. The system encourages thoughtful placement of armor pieces to shield vulnerable areas during combat.
Because armor behaves as a physical barrier, players can experiment with layering and positioning to maximize coverage. The realistic physics also affect how weapons interact with enemies and the environment, adding depth to each encounter.
- Observe how armor pieces conform to your character’s silhouette before engaging enemies.
- Compare different material combinations to see which offers the best surface coverage.
02 / THE GUIDE
Fully Destructible World
Every element of the environment—terrain, buildings, trees, rocks—is completely destructible. Players can reshape the landscape to create new pathways or eliminate threats, making each encounter dynamic. Destruction is not limited to combat; it can be used strategically to build or block routes.
The destructible nature extends to both natural and man‑made structures, allowing for creative problem‑solving. Whether you need to clear a forest for a line of sight or bring down a building onto a horde, the world reacts realistically to your actions.
- Test how different structures collapse to plan defensive positions.
- Use environmental destruction to funnel enemies into traps.

03 / THE GUIDE
Insane Vehicle Construction
Combine any building materials to craft mobile fortresses, giving you unprecedented freedom to design transport that suits your playstyle. Lua scripts provide precision control, yet the system also offers plug‑and‑play options for those without coding experience.
Vehicles can serve as moving bases, weapons platforms, or escape mechanisms. The ability to script behavior means you can automate defenses or create unique movement patterns, expanding tactical possibilities beyond conventional combat.
- Experiment with different material mixes to balance durability and speed.
- Compare scripted versus plug‑and‑play vehicle controls for ease of use.
04 / THE GUIDE
Procedural Biomes
The game features ten randomly generated biomes—including forests, ruins, deserts, canyons, rainforests, and snowfields—that blend into a seamless, endless world. Each biome presents distinct visual and tactical challenges, encouraging exploration and adaptation.
Because biomes are procedurally generated, no two playthroughs share the same layout. This variety influences resource availability, enemy types, and optimal building strategies, keeping the experience fresh across sessions.
- Observe how terrain types affect vehicle handling.
- Compare the defensive options each biome naturally provides.
05 / THE GUIDE
Combat & Oppressive Bosses
A wide variety of firearms and powerful traps give players multiple ways to confront the infected. Night hordes run fast, demanding quick reactions, while bosses present intense, oppressive challenges that test your constructed defenses.
The combination of fast‑moving enemies and destructible surroundings forces players to balance offense, defense, and environmental manipulation. Traps can be placed strategically to thin out hordes before a boss encounter, adding layers to combat planning.
- Test different firearm types against fast night hordes to find the most effective range.
- Compare trap placements to see which configurations best thin out enemy waves.
