Survive the Experiment.

Phantom Containment is an open-world anomaly survival horror game set on Helix Planet, a massive containment world consumed by hostile entities, aberrant species, anomaly outbreaks, and violent factions.

You are not a hero.
You are a specimen.

Trapped inside a classified experiment alongside thousands of prisoners, exiles, scavengers, zealots, failed experiments, and hostile survivor groups, your only goal is survival.

Escape is impossible.

To the civilizations beyond the stars, everyone inside Helix Planet is expendable.

Scavenge what you can.
Build what you must.
And survive long enough to uncover what Helix Plant was truly built for.

🌍 A Massive Living Containment World 🌍

Explore a huge open world filled with:

abandoned research complexes

ruined settlements

underground bunkers

corrupted wilderness

anomaly zones

aberrant species territories

hidden laboratories

containment facilities

forgotten ruins

The world evolves throughout development with expanding regions, new biomes, environmental systems, entities, and survival threats.

Each biome introduces unique:

• anomalous activity

• environmental hazards

• resources

• weather conditions

• entities

• aberrant species

• survival challenges

What feels calm during the day may become deadly after dark.

The world constantly changes through:

• dynamic weather

• anomaly storms

• roaming entities

• containment sweeps

• faction raids

• territorial conflict

• containment breaches

No area stays safe forever.

👁️ Planet Is Alive 👁️

Anomalies are not limited to scripted encounters.

They exist everywhere.

Different regions of the Plant are influenced by powerful entities and unknown forces that react to:

• noise

• structures

• lights

• player activity

• stored artifacts

• territorial expansion

You may:

hear voices from empty structures

see distant figures observing your movements

experience hallucinations and reality distortions

attract hostile entities to your settlement

discover signs that something entered your shelter during the night

Build in the wrong territory —
and your settlement may become part of the hunt.

Nowhere is completely safe.

🔦 Investigation & Containment 🔦

Detection and containment equipment are essential tools for survival.

Use specialized equipment to:

• detect nearby anomalies

• identify hostile entities

• track aberrant species

• stabilize dangerous areas

• secure your settlement

• recover anomalous artifacts

• survive entity encounters

Prepare your defenses using:

protective devices

containment tools

anomaly scanners

traps

containment systems

environmental monitoring equipment

Knowledge is often more valuable than weapons.

⚒️ Build, Expand & Defend ⚒️

Gather resources, hunt wildlife, craft equipment, and build shelters ranging from improvised camps to heavily fortified survival compounds.

Expand your base with:

• crafting stations

• storage systems

• farms

• workshops

• defensive walls

• power systems

• containment chambers

• research facilities

But large settlements attract attention.

Hostile factions, containment forces, scavenger groups, zealots, and anomalous entities may raid your territory to destroy structures, recover artifacts, or eliminate survivors.

If your defenses fail, you may lose:

supplies

equipment

territory

and parts of your settlement

Survival means constantly rebuilding.

⚔️ Other Survivors Are Just As Dangerous ⚔️

You are not alone on Helix Planet.

Encounter:

• hostile prisoner factions

• scavenger groups

• rogue survivors

• zealot factions

• containment operatives

• corrupted individuals

• escaped experiments

Some fight for survival.
Others fight for power.

As the Planet descends deeper into chaos, conflict between survivors becomes unavoidable.

Choose how you survive:

stealth and evasion

direct combat

traps and defenses

scavenging

containment tactics

strategic preparation

Overconfidence gets people killed.

📈 Survival, Skills & Progression 📈

Develop your survivor through long-term progression and skill-based gameplay.

Train abilities including:

• mining

• woodcutting

• fishing

• farming

• cooking

• tailoring

• construction

• stealth

• lockpicking

• hunting

• crafting

• combat

• alchemy

and more

Manage critical survival systems such as:

hunger

energy

temperature

oxygen

inventory weight

environmental hazards

anomaly exposure

Every decision affects your chances of survival.

📚 Uncover the Truth 📚

Hidden across Helix Planet are the remains of failed containment operations, abandoned experiments, collapsed facilities, and forgotten civilizations.

Recover:

anomalous artifacts

entity samples

experimental technology

ancient relics

classified records

containment logs

research archives

The deeper you explore, the clearer the truth becomes:

The Planet was never built as a prison.

It was never built to contain anomalies.

It was built to determine which species could survive them.

And the experiment is still ongoing.
