Event Guide[]

  • Stages are likely required to be cleared twice. If teachers don't have the upgraded event students; It's easier to clear the stage twice: to get the 3★, bonus student drops, and thus the maximum reward.
  • Once an area has been perfectly cleared, at 3★. The stage reward given is always the highest recorded drop, including the bonus from the students.
    • Using the "Skip or Rush" function will record the highest drop.
  • In this event, teachers can farm a lot of items:
    • Materials (Ooparts)
      There are 4 types of materials that teachers are able to obtain and each can be obtained from tier 1 to tier 4. There is no event bonus for these materials.

      • Teachers will switch between the Field Operation and the event story in order to progress the main story.
    • On the map, any location with a red background is a battle stage, and any location with a purple background is an Infiltration Stage.

Trivia[]

  • The entire Infiltration/Undercover stages are all reminiscent from Metal Gear games and most of its series.
  • Neru being able to knock out enemies is similar to Solid Snake doing CQC on enemies, stunning them for a brief time but with a few exceptions, once the enemy is knocked out, it will despawn and never appear again.
  • Seia interacting with the Microphone on Rio's hideout is a nod reference to the "Seia Muted" meme, a meme that has been canonically inserted by the developers and Yostar.
  • In the global server, this event is the first event released after the addition of PC client.
