Before playing the field trip, Baldi will talk about how to play it. The introduction can be skipped by pressing the ESC key.
Completing a field trip will reward the Player up to 3 items and 300 You Thought Points depending on the number of yellow stars shown on the results screen. However, if the Player loses all yellow stars, they will not receive anything.
Note: Italic texted field trips are currently unavailable.
The Player was meant to visit and explore around the field trips freely at first. This applies to the first two field trips (camping and farm), as they were available on the field trip demo, Kickstarter exclusive demo, and Baldi's Basics Plus from V0.1 to V0.2.2. Upon release of the update patch V0.3, camping field trip is revamped into simple UI-like minigames first, then the same goes on the farm field trip in V0.3.2.
Even if the Player gets just 2 stars at the end, they still earn items gained from achieving 3 stars.
However, if the Player earns only 1 star, then they only get one item.
A new field trip was planned to be added in V0.2 of Baldi's Basics Plus, but it was canceled. However, there will be new field trips in future updates.
Prior to V0.3, the Player would lose all items from the Super Schoolhouse from the inventory when failing a field trip.
When the Player is caught by Baldi, the jumpscare noise will continue to play for a few seconds longer than usual after being teleported back to the main game. This no longer happen in V0.3 because the mechanic became completely different.
Since V0.3, the Player can no longer pause the game during the field trip in order to prevent cheating.
In V0.1.5 of Baldi's Basics Plus, if other characters try to chase the Player during field trips, they will fall through the ground and flee away from the Player. Cloudy Copter and Gotta Sweep still work fine as they do not have a chasing mechanic.
When entering a field trip, some game mechanics will still appear on screen (such as detention timer and subtitles), however, the mechanics will freeze during the game, but still go on during the field trip.
Entering a field trip while Baldi eats An Apple will mute all sounds after a few seconds. While muted, the next phase will start immediately after the current phase is over. This also applies to some music like School and Dance until closing the game.
