About System of Souls

System of Souls is a puzzle game set in 2155, when Earth’s environmental conditions have become unsustainable and humans transfer their souls into robotic bodies to survive. You play as L-064N, who wakes in an ION droid after an accident with no memories. ION says it rescued him in a pitiful state; although he cannot communicate, his robotic body has technological abilities far beyond those of his human body.

L-064N’s story

To recover his memories and learn what ION is doing, L-064N must complete trials designed by Aura, a highly developed AI at the company’s facilities. The trials explore aspects of his memories, including ideas, personality and feelings. As he progresses, L-064N acquires or improves skills that help him explore and solve tests Aura has simulated within his psyche.

The trials reveal more about L-064N’s story, Aura’s knowledge, and characters with varied histories. You also face challenges confronting ION and find clues to the enigmatic world around you.

Puzzles and challenges

You solve complex puzzles and look for ways to overcome the challenges in each trial. The puzzles become progressively more difficult, with the experience adapting to the player’s ability to solve them.

The ION complex

Explore science-fiction environments and the rooms of the ION complex. The story follows L-064N as he seeks to recover his memories, discover who he is, and uncover the truth about ION and Aura.
