A survival horror game where you must work alongside an 8-bit computer to overcome deadly challenges. Use unique weapons and equipment to explore a dark, hostile exoplanet.

With its 8-bit interface as your lifeline, you must challenge the planet’s uninhabitable dark surface. Descend into its hostile underworld. Study its alien flora and gather cryptic scientific data—but stay vigilant.

Yet as you delve deeper, the planet’s physical laws twist. Time fractures, memories distort, and the boundaries of your identity dissolve. Survive the suffocating darkness—but remember: the greatest threat may not lie in the void around you… but within your own unraveling mind.


Due to the computers 8-bit graphical and communication limitations, you must interpret 2D pixelated visuals and translate them into real-time solutions to overcome various challenges.

Here, you can rest, store items, and get new missions. But something feels wrong. You were supposed to be alone. So why does it feel like someone — or something — is watching you?

You hear footsteps in the empty corridors. See shadows that don’t belong to you.
Maybe you’re not alone. Or maybe you never were.
