X300

It was never meant to be understood. 

X300 is a first-person psychological survival horror game set across and beneath the Australian Outback.

Experience the Australian Outback as you've rarely seen it before. Venture beyond the familiar image of Australia into a vast, isolated landscape shaped by Cold War secrets, abandoned military sites and a history buried beneath the red earth.

Search for your missing brother across an open desert region enclosed within the remains of a sprawling Cold War military reservation. Choose your own path through forgotten survey camps, derelict homesteads, weather stations and abandoned installations as you search for supplies, clues and ways underground.

But the further you travel, the less certain the landscape becomes. Roads do not always lead where they should. The wildlife has changed. And something is following you across the desert.

Beneath your feet, the Facility offers a different kind of journey: a tense, story-driven descent through sealed corridors, analogue machinery and forgotten experiments. The Facility is still operating, and it knows you're here.

WHAT YOU’LL DO

Search for your missing brother across an abandoned Cold War military reservation lost in the Australian Outback. Explore its open desert, forgotten camps and surface installations, choosing your own path as you search for supplies, clues and hidden ways into the underground Facility below.

Scavenge scarce resources, survive the landscape and uncover the remains of a military operation that was never meant to be found.

OPEN EXPLORATION ABOVE GROUND

Follow abandoned roads, investigate distant structures or venture off the track in search of what others left behind. Watch the horizon. Read the weather. Know when to keep moving and when to find shelter.

BELOW GROUND, THE RULES CHANGE

Descend into a more claustrophobic, story-driven journey through the Facility. Operate analogue machinery, navigate sealed corridors and solve environmental puzzles as you uncover what happened here — and why the Facility never truly shut down.

The machinery still runs. Doors still require authorisation. Orders are still being issued and something unseen is studying how you respond.

YOUR PERSONNEL DOSSIER

“Funny thing about this place is it keeps records.”

Every decision you make contributes to a classified psychological profile. The Facility records what you investigate, what you ignore, who you trust, whether you obey and how you respond under pressure.

At the end of X300, the Facility generates a personalised dossier based on the way you played and the person it believes you became.

Save it, share it or print it as your own Cold War souvenir from X300. The dossier does not tell you who you think you are. It tells you who the Facility believes you became.

OH, and one last piece of advice: “And if you hear someone calling from beyond the fence, keep walking. Especially if they know your name.”
