How it's possible ? Platine Arma 3 on Xbox

Both Xbox and PC games will show up for your friends if they are using Windows 10 and and are logged into the Windows 10 Xbox App. Your friends are playing Arma3 on a PC, not on a console.

Will arma 3 ever be on xbox?

Unlikely,

However, I have heard that ARMA 4 is in development for PC and consoles,

It's very likely it will release on PC first before consoles, but there's very little info on ARMA 4 at the moment.

Good morning

Yes, it is possible:

One way to achieve this is by using voice recognition software such as Windows Speech Recognition, Dragon NaturallySpeaking, or VoiceAttack.

Here are the steps to set up voice commands in Arma 3 using VoiceAttack:

Install VoiceAttack on your PC.

Open VoiceAttack and create a new profile for Arma 3.

Configure the speech recognition engine to recognize your voice. You may need to train the software to recognize your voice accurately.

Create a list of voice commands that you want to use in Arma 3. For example, you could say "Move to Alpha" to order your troops to move to the Alpha position.

Map the voice commands to keyboard or mouse inputs in Arma 3. For example, you could map the "Move to Alpha" command to the "M" key on your keyboard.

Test the voice commands in Arma 3 to ensure that they are working correctly.
