In Freeplay, the player is free to explore any map outside of a regular game environment. Several "dummy" Crewmates are positioned around the map and do not move or act in any way, other than by randomly voting. A laptop can be accessed near the emergency button, which allows for the player to customize their tasks freely, as well as whether or not they are An Impostor. All abilities from the classic game, such as Sabotaging and reporting, are usable.
Freeplay is an excellent way to practice routes as both a Crewmate and An Impostor, a player should always take advantage of what they can do on each map and plan the best ways to use this to their advantage. Playing this mode can help increase players' chances of victory during a typical play session. However, when all players are killed, all tasks are completed, a critical Sabotage's countdown ended, or when all the players are voted out, all "dummy" Crewmates and tasks will be reset. It is often considered a "training mode".
- Freeplay is currently the only mode with non-player characters.
- Freeplay was originally called "Free Play Mode".
- When an emergency meeting is called, or a dead body is reported, all "dummy" Crewmates automatically either vote any living character or skip voting without sending messages in the chat. This can result in the player being ejected and "dummy" Crewmates voting for themselves.
- In Freeplay, there are six "dummy" Crewmates on both The Skeld and MIRA HQ, four "dummy" Crewmates on Polus, and nine "dummy" crewmate on The Airship.
- The "dummy" Crewmates' colors in order from Dummy 1 to Dummy 9 are Red, Blue, Green, Pink, Orange, Yellow, Black, White, and Purple. In Freeplay on Polus, the color order is the same other than the fact that there is only Dummy 1, 2, 3, and 4 while in Freeplay on The Skeld and MIRA HQ, the color order is the same other than the fact that there is only Dummy 1, 2, 3, 4, 5, and 6.
- The order of the "dummy" Crewmates is the same as the order colors are listed when customizing one's color.
- If the player is one of the colors used by a "dummy" Crewmate, the color order of the "dummy" Crewmates will stay the same but include the player's color within the order. Dummy 6 will become Black in Freeplay on The Skeld and MIRA HQ, following the colors' order when customizing one's color. Similarly, Dummy 4 will become Orange on Polus and Dummy 9 will become Brown on The Airship.
- Freeplay is currently the only mode where a player can switch from a Crewmate to An Impostor and vice versa.
- Because the game starts right away without the starting scene, players cannot change their character's appearance while in Freeplay and will default to their appearance in their last game.
- In an older version of Among Us, when a critical Sabotage was called, venting within one second before the time runs out caused The Impostor to be invisible. Killing a Crewmate or venting would result in the appearance of The Impostor.
- The Impostor could move freely while in this state, and the arrows were still shown. The Impostor could jump out of any vent, including ones not in the current vent chain.
- If their role was switched back to Crewmate, they could vent, but only the group of vents they entered to create the glitch. The venting animation did not show, but the player would be teleported to the other vents they pressed the arrows to get to.
- The "dummy" Crewmates can eject the player out and if they are a Crewmate, this allows them to play as a ghost.
- The Reactor Meltdown and Reset Seismic Stabilizers Sabotages cannot be fixed in Freeplay unless a body is reported.
- The computer where players can customize their tasks is called the Task Tester 2000.
- Pressing the emergency meeting button as Fortegreen in Freeplay will result in a softlock.
- The game options are not interchangeable as to a typical lobby.
- In Freeplay, if the player is a ghost and becomes An Impostor via customize, the game will reset everything to its standard state and resurrect the player. However, the player's task list will say both "Sabotage and kill everyone" and "You are dead. Finish your tasks to win." If they switch back to a Crewmate, the task list will still say that the player is dead even though they are not.
- When a Sabotage was happening when The Impostor killed a Dummy Crewmate and won, the Sabotage still remains, without resetting the countdown.
- If the player is a ghost and finishes their tasks, the game does not end despite the taskbar being full. This is most likely a glitch.
- If the player kills a dummy Crewmate and then switches back to a Crewmate and gets ejected, it is possible to see a ghost dummy Crewmate.
- A player can always call nine emergency meetings in a single Freeplay game, which the number used to be one.
- If a player runs out of emergency meetings, they can switch from Crewmate to Impostor (or vice versa) and back again to reset their emergency meeting count.
- It is not possible for a dummy Crewmate to be Cyan or Lime. This is because there is a maximum of 9 dummies (10 players) in Freeplay, and Cyan and Lime's color IDs are 10 and 11.
- In Freeplay, it is possible to do multiple Divert Power tasks and Upload Data tasks.
- This is the only gamemode wherein An Impostor could have a partially-done task or task list.
