AETHUS is a sci-fi simulator in which the main goal is to establish a self-sufficient life amid the ruins of a failed research initiative. Gameplay relies on a complex life-saving system that requires monitoring thirst, hunger, and equipment capacity. Exploration takes players into misty underground jungles, scorching magma lakes, and arid caves. To establish a safe zone, outposts are modularly constructed, allowing for the placement of dozens of processing stations. Inside these living quarters, you can breed fish, cultivate flora, and sort precious stones.
