// RIVERS STATE · NIGERIA · 72 HOURS AFTER THE BLACKOUT

THE LOST CITY PORT HARCOURT

A cinematic third-person horror-action survival game. Entire neighbourhoods are empty. Generators still run inside abandoned compounds. Something has been living beneath the city for decades — and it knows you're here.

01 — THE TRANSMISSION

“If you're hearing this… don't come looking for us.”

Then the signal died.

During The Blackout, Port Harcourt went dark in a single second. By morning, the people were gone — from Rumuola to Borokiri, from Diobu to Eleme. Cars stood with their doors open. Pots were still on the fire. Phones lay in the streets, still ringing.

You enter the city searching for the missing. Their journals, voice notes and photographs point to the same thing: a group of investigators had been mapping strange structures beneath the city — structures older than the city itself.

The Blackout was not an accident. Someone intentionally opened something that should have remained buried.

03 — CONCEPT FIELD GUIDE

They were here before the city.

An illustrated concept guide from the world of the game. Some creatures shown here belong to ideas beyond this five-chapter release.

Original entities shaped by Niger Delta legend, urban rumour and the long dark of a Port Harcourt night. Each one hunts differently. Each one can be survived — if you learn how. Hover or tap a file to open it.

04 — SURVIVAL SYSTEMS

You can't trust what you see.

Health, stamina, batteries and ammunition keep you alive. The Fear meter decides what's real. Try the live HUD below — every button changes the state of your survivor.

DURABILITY

0–30 · Uneasy

Footsteps behind you. Dogs barking somewhere far away. Normal — probably.

30–60 · Shaken

Breathing grows loud. Sounds become directionally unreliable. Shadows linger where nothing stands.

60–85 · Terrified

You hear your name whispered. False enemies flicker into existence. Hallways stretch.

85–100 · Breaking

Doors appear where there were none. The environment rewrites itself. Nothing is certain.

🔦

Battery Management

Flashlights drain. Some creatures hate the light. Others follow it.

🔫

Tactical Combat

Real recoil, slow reloads, weapon durability and scarce ammo. You can't shoot everything.

🎒

Weight Inventory

Grid-based pack. Every medkit you carry is a magazine you leave behind.

📻

Radio Network

Listen to recordings, survivors — and things that only pretend to be human.

🧗

Full Traversal

Walk, sprint, crouch, hide, climb, jump, swim and drive across a connected region.

🧩

Environmental Puzzles

Restore power, reroute pumps, decode broadcasts and open what was sealed.

05 — THE GARAGE

Everything left behind still runs. Mostly.

Abandoned vehicles across the city — each with fuel, damage, working lights and doors, tyre damage, unique handling and storage. Some need keys. Some need repairs. Some only exist in one district.

06 — INTERACTIVE SITE PROFILE

Future chapters

08 — BENEATH THE CROSSROADS

Follow the signal to its source.

The recordings connect the missing people, the silent houses and the attacked convoy. The final chapter brings the investigation beneath Rumuokoro. What is waiting there has learned how to call you closer.

09 — ORIGINAL SCORE

Silence is the warning.

An original soundtrack built on the feeling of 1990s–2000s Nigerian horror: low distorted drums, old-style percussion patterns, haunted vocal textures, radio distortion and dark synths. No samples. No borrowed audio.

The music goes almost completely silent right before major encounters. When it stops — run.
