It would be great if they added a walkie talkie that the inventor can create to the game.
although I doubt it will help (in the same way there are devices that the inventor has that are useless, such as the danger detector)
This obviously serves to communicate with your team through the walkie talkie.
When you press the left button, a menu will appear like the one the neighbor uses to disguise himself, the list of players who have a walkie talkie appears.
I guess it would cost two gears
