Test procedure is one of the random events for Baldi's Basics Plus.



The lockdown door.

The test procedure event consists of lockdown doors in some hallways which are introduced on floor 2, although the event is introduced on floor 3.

A closed lockdown door.

When the event starts, the player will hear a 10-second countdown, and once it is over, all the lockdown doors will close, preventing the player and other characters from getting through for a few seconds.

Some lockdown doors may shut later than the other doors. In other words, not all lockdown doors close and open at the same time.

A button that can be clicked to open/close a lockdown door.

Some of them can also be opened or closed anytime by pressing the nearest buttons. These doors are not affected by this event.


Although there are no events in challenges, there is one lockdown door in the Stealthy Challenge and Grapple Challenge each.

  1. "Here's something new that I just got pretty much fully working: Subtitles! They change location and sized based on the direction and distance of the sound's location. I did this because listening for noises and where they're coming from is an important aspect of Baldi's Basics." - mystman12. October 18, 2018. Twitter
