Overview[]
Event stories are typically short and can switch to different characters' perspectives, unlike Main Story, which follows Ruka's. In most events, players are able to assign their own units, though some may have a pre-set squad instead.
While event stories generally are independent from the main story, some expands or continue on its plot. As such, it's strongly recommended to complete the main story to fully enjoy everything the events have to offer.
All stories will be archived in the "Event" section of the game, except for collaborative and campaign stories.
Mechanisms[]
Schedules[]
Most event story still operates per schedule-basis, however as event story are either shorter, independent or focuses on different characters, the scheduling system will only work as a time reference of the scenes in the stories. However, most stories still adhered to events occuring within the timeframe given as most characters live in a military base with relatively fixed schedule.
Most event story will generally include a prologue, body story up to Day 3, and sometimes an epilogue. However it is not a must, as some events may have different ways to convey their story.
Some special cases include:
- Behavioral Observation Report No. 1186 retells Chapter 3 events with reversing the order of the day from the main story.
- The Oracle and the White Lily uses Chapter instead of Days as the story retells Chapter 2 events too.
- Ohshima Family Tales uses weeks instead of days
Maps and Dungeons[]
While most of it keeps the standard dungeon mechanics of the game, some events experimented with some unique dungeon types throughout the game. For example, The Friend From That Day event introduces a "free-moving" dungeon where players can explore the map in a free 360 degree view instead of sticking with restricted 2D-view dungeon.
Minigames and other mechanics[]
Some events added some interesting minigames that may add to the gameplay experience of the game. For example, New Year! 31-A's Desert Island Survival Story ~It's Game Over Sometimes~ event adds a "cooking" minigame where player can cook food based on ingredients found in the event, and Ohshima Family Tales event adds a "shopping simulation" mechanic where player can arrange and sell items from the event.
The minigames offers rewards for the events, and some like Ohshima Family Tales event may even affect the story outcome.
