The Butterfly Sign: Human Error is the second chapter of a first-person detective story. Jack is the sole survivor and only witness of a terrorist attack on Memority hospital, where an experimental drug called Rammex was developed. The explosion and fire destroyed part of the hospital, killed its staff and patients, and left Jack with only fragments of his memory. Confined to a hospital bed, he uses Rammex to revisit his memories and investigate the attack, with help from Dr. Romanov, Memority’s chief scientist and the drug’s creator.

Jack’s memories

Most of the game takes place in Jack’s memories, while the real world consists of the hospital bed where he lies. Events unfold in the past and present simultaneously. As Rammex brings back what Jack has known, he can act and make choices within his memories; he may even find a Rammex device there and potentially use it. The chapter also introduces previously inaccessible memories.

The story follows the three chapters of The Butterfly Sign. In Necessary Evil, Jack uses Rammex to recover his memories and help Dr. Romanov identify those responsible for the attack, but the further he goes, the more he sees what happened as a necessary evil. In Human Error, he investigates the hospital’s work on Rammex, which was intended to restore lost memories and quickly repair nerve cells. As he turns through his own mind, he begins to question how real his world is and whether it is a beautiful lie. In Wreck of my Warship, Jack collects the pieces of his memory and goes to the dam, where he last saw the mercenaries. There, he finds someone attempting suicide by jumping from the dam. Realizing he has been there before and that the answer is in his mind, Jack follows by jumping in the hope of remembering.

Investigate Memority

You explore Memority hospital and its grounds, uncover its secrets, and piece together what happened there. You investigate murders, search for clues, compare facts, solve puzzles and avoid obstacles. Some memories distort into looped spaces: attempts to leave a location bring you back into it, and you must solve the puzzle to break the loop and escape.

Choices and difficulty

Non-linear dialogues depend on your location, and choices—sometimes minor, sometimes important—affect the story and its ending. Your decisions shape the outcome and whether Jack reaches the truth. Several difficulty levels are available, including an easiest setting for players who want to focus on the story and a hardest level where a single death restarts the game.

Sound and atmosphere

Rooms have distinct soundscapes suited to their style and mood. Individual details, such as lamps and water drops falling from the ceiling, have their own sounds.
