The Solus Project Alone on an alien world

Survival here serves the journey rather than the other way around. You eat, drink, sleep and watch your body temperature, because days on Gliese-6143-C climb past 45C and nights drop below -30C. Getting wet matters, so does exhaustion, and walking uphill costs you. You scavenge supplies from your ship's scattered wreckage and craft simple tools from what the planet offers: strike two rocks together and you have a cutting tool. Resting spots with food and water dot the world, so the pressure stays steady instead of crushing. And you can tune it all yourself, from a hardcore run to a relaxed stroll across an alien shore.

The planet runs a full simulation: temperature, wind, humidity, cloud cover, ocean tides driven by the moon, plants that grow and rot with the climate. Storms roll in, earthquakes shake the ground, and then there are the tornadoes, meteor showers and lightning. When the sky darkens and the wind picks up, you drop what you are doing and look for shelter, because getting caught out in a meteor shower is a fast way to die. The weather is a highlight: it turns a quiet walk across an island into a scramble for cover, and it makes the world feel like a place with moods of its own.

Megalithic tombs stand all over the planet, which raises an uncomfortable question: you were clearly not the first intelligent being here. Who built them, where did they go, and what happened? The story unfolds as you explore, through crew notes and the writings and murals the dead civilization left behind, so reading every document you find pays off. There are over 500 to discover. Earth is gone, the colony fleet waits near Pluto, and your job is to rebuild a communication device and phone home. The tone is classic science fiction: serious, quiet, and increasingly uneasy the deeper you dig.

The world is five islands linked by dark cave systems you must traverse to travel between them, making ten large handcrafted levels in total. The layouts are old school in the best way: complex, full of keys and locked doors, with secret areas hidden inside other secret areas. Over 200 secrets are tucked away, some the size of entire levels in other games, and hundreds of upgrades reward the curious. You play first person with no obvious enemies and very little hand holding. It is just you, a flashlight, and a tunnel that keeps going further down than it has any right to.
