Shred the Secrets supports multiplayer servers, and the official Perfect Attendance badge requires completing Ending 2 “as a full squad.” Public sources do not define the live full-squad count or prove an optimal party size.
Divide visible work
At the start of each room, give players clear jobs: document collection, scrap vacuuming, shredder delivery, and a final sweep of doors or side areas. Announce when an area is finished so the team does not repeatedly search the same desks while another corner is ignored.
Keep carried paper moving toward a shredder, and agree before spending shared or run-specific cash if the current build makes that relevant. Each player should read the live Skill Tree and class interface rather than relying on unverified effects.
Protect the ending attempt
For Perfect Attendance, confirm the party is full according to the live lobby or run UI before starting. Keep the same squad together through Ending 2, and check badge awards after the completion sequence. The badge description proves the relationship between a full squad and Ending 2; it does not reveal the ending choices or whether a disconnect invalidates the run.
Do a normal squad clear before combining Ending 2 with a speed or every-document objective. One goal at a time makes a failed award easier to diagnose.
