Loop 4

Loop 4 is the fourth loop of Gnosia.

Summary
Loop 4 opens in the Cafeteria, where the player is eating with Shigemichi when the alarms signifying Gnosia infectees are onboard go off. Shigemichi is annoyed by this, wishing they could get some peace and quiet. He changes subject, asking about what an Engineer does; as it turns out, the player is the Engineer in this loop and told Shigemichi this moments prior to the start of the loop. Whether the player expresses knowledge about their role or not, Shigemichi insists that they finish eating before meeting up with the others. He uses his ray gun on his ramen, revealing that rather than being a weapon it can be used to analyze the composition of food.

Upon arrival to Main Control the player and Shigemichi are briefly chastised by SQ for being late, but the subject quickly shifts to the matter of the Engineer. Setsu notes that they can't force the Engineer to step forward and reveal themself, as doing so would put them at risk of being targeted by the Gnosia. Whether the player decides to step forward or not, one of the Gnosia will falsely claim to be the Engineer themself, forcing the player's hand (if they choose not to do so anyway, Shigemichi will force the player's hand due to them having told him their role earlier).

After the debate, Stella - who cannot be voted off on Day 1 - approaches the player and commends them for their bravery on stepping forward (even if they didn't do so willingly), declaring that she believes they are the true Engineer. She expresses concern, however, that the player will be attacked by the Gnosia as a result, suggesting they would throw their own fake Engineer under the bus in order to get rid of the real Engineer. Nonetheless, she promises to protect them before returning to her room.

On Day 2, it becomes apparent that no one has been attacked. The crewmates question this, and Stella explains there must be a Guardian Angel. The Guardian Angel, she explains, is someone with warp-related credentials that allow them to delay the warp slightly, preventing the Gnosia from attacking their intended target. They only have enough time to protect one specific person, however, and cannot protect themself.

During the debate, if the player doesn't take up the entire debate someone will ask if Stella is the Guardian Angel. She denies this, but after the debate - should she avoid cold sleep and should the humans not achieve victory that day - the player can meet with her at night and have Stella express her concern that the Gnosia almost certainly wouldn't be convinced. She says her goodbyes, and should the player thank her for her kind words she'll express that such a reaction is all she needs to be able to face the end at peace.

Stella will always be eliminated on Night 2; the only way for her to survive this loop is for the crew to put all of the Gnosia into cold sleep by the end of Day 2, though there is no special dialogue for achieving this.

Day 2
Depending on who's around on Day 2, dialogue will be assigned to varying characters. Where variant dialogue exists, the characters who may speak are listed in descending order of the game's apparent preference.
