Everything you need to survive Gliese-6143-C is somewhere in the environment. Managing your inventory and knowing how objects interact with each other is key in
The Solus Project. Knowing what to look for, knowing how to use items, and knowing when to use them: those are all the skills you need to keep going. Your health is tracked using several important metrics, such as thirst, hunger, and temperature. While they tend to drop considerably faster than they do in real life, it's easy to forgive for the sake of the overall experience.
If you play this game, play it with headphones and completely in the dark. The current build of The Solus Project isn't the most technically impressive game you can currently play, but it inflames your imagination with its alien landscapes and stunning cosmic vistas. At one point, I saved my game and ignored my most pressing needs in favor of simply watching the mesmerizing day/night cycle at work. Gliese-6143-C is far closer to other planetoids than Earth is, and watching these massive spheres silently orbit can be an awe-inspiring, unnerving experience.
