The game is divided into two routes: [[JustForPun Root]] A, and Root B. Root A tells the story of Watase Kasasagi, the leader of a rescue team group named "SIRIUS". On September 16th, 6:16 A.M., an emergency occurs in the "6th Laboratory of Atomic and Biological Organization", nicknamed LABO, and SIRIUS is sent to deal with it. While there, Watase suddenly comes a "monster". Overcome with intense pain and an indescribable fear towards the monster, he runs away, only to black out in a hallway. When he wakes up, he is greeted by his subordinates, Lieutenant Kazami Tachibana, and new recruit Jun Moribe. However, he realizes he has lost his memories. As it turns out, LABO has been completely sealed off from the inside, and the LABO itself is full of radiation due to a meltdown. Despite this, Watase decides to take action and continue the search for any remaining survivors in LABO...

* ManOnFire: Many of Root A's Bad Endings feature this.

* NotGoodWithPeople: Salyu, who has a very hard time understand other people's emotions and their changes in emotions. At one point, she likens it to how normal people can't understand insects' emotions. [[spoiler:Justified, as the entire week of Route B is the first time in her life she's ever interacter with others apart from Miyoko.]]
* OfficialCouple: [[spoiler:Watase/Kazami.]]

* OrdinaryHighSchoolStudent: Natsuhiko.

* KillEmAll: [[spoiler:The Root A Normal Ending, which ends with everyone except Watase dead.]]

* [[spoiler:EverybodyLives: With the exception of Nagisa.]]

* [[spoiler:UnreliableNarrator: The prologues of both Root A and Root B leave out key details that aren't revealed until later.]]

* [[spoiler:WeAreAsMayflies: Inverted- Communicators in general have shorter lifespans than humans (due to the gene mutations in the [=IGF2R=] gene that determines if one is a Communicator), with Level S Potential Communcators only have about 20-30 years of lifespan.]]

''Would you destroy everything for someone else?''

''Would you kill someone for the sake of everything else?''

* YouGottaHaveBlueHair: Kazami (purple), Jun (green), Yuuri (lilac).

* FiveManBand: Root A's cast, although the first two roles tend to fluctuate due to Watase's amnesia.
** TheHero- Watase/Kazami
** TheLancer- Kazami/Watase
** TheBigGuy- Jun
** TheSmartGuy- Ukita
** TheChick- Yuuri
** TheSixthRanger- Ena

* GoOutWithASmile: [[spoiler:Nagisa.]]

* CryForTheDevil: [[spoiler:As Natsuhiko encounters more fragments of Nagisa in different people's minds, he feels more and more sympathy for her each time, to the point that by the end, he wishes there was a way he could have saved her. In fact, one of the scenes where he talks to one of her fragments is named "Sympathy For The Devil".]]

* MonsterSobStory: [[spoiler:Nagisa, who, while having no qualms about corrupting people's memories and states she can never be changed, still was forced to become what she was against her will.]]

* RelationshipVoiceActor: Akane Tomonaga (Jun), Creator/MegumiToyoguchi (Ena), and Shunsaku Nishigaki (the commander of Sirius) all played roles in one of the director's former works, ''VisualNovel/{{Remember11}}''.

* TooSoon:
** The game (dealing with a meltdown of a nuclear reactor) had its development halted for four months due to the 2011 Japanese earthquake, which lead to the partial meltdown of several nuclear reactors.
** [[spoiler:Which is ironic, given that it turns out that there is no nuclear reactor (and therefore no meltdown) in LABO.]]
