Friends
You always have the opportunity to add any player as a friend. To do this, you need to know their ID. It is important not to lose your friends' IDs, so you can always return them to your friends list. For example, when you transfer progress through the Support Team, the friends list is NOT transferred.
In addition, you can add players as friends after a battle in team modes. To do this, click the “Results” button in the lower left corner.
After this, a screen with rewards will appear. There, you will see a button with team ratings — click on this button and select the player you want to add as a friend.
To add a friend, click the button to the right of the player's nickname.
If you want to delete a friend from your friend's list, click on the friend's trophies, and then the delete button will appear.
Another option is an invitation that you can send to any social network. When they follow the link, they will be taken to Google Play or the App Store. Once your friend has downloaded the game, you can add them to your friends list and climb to the top of the Bullet Echo leaderboards together.
This link can be found in the "Friends" tab. Besides the fact that you can share the game, you can get cool rewards! Check out the "Invite Friends" tab and play with your friends!
Team
By clicking on the "Team" button in the upper right corner of the screen, you can create your own team and invite your friends (who are currently online) to it or join an existing one. For this, you will need a team ID.
Your friend can share their Team ID or invite you in-game. In this case, the battle will not begin until all the fighters in the team have confirmed their readiness. Teams can be created and disbanded as often as you like, as there is no limit to the number of teams you can create in the game.
You can also use voice chat when playing in a team. You will need to have microphone access turned off in your game settings.
Please note that you can team up with two friends to play "Battle Royale" mode and up to four friends to play the "Squad vs Squad" and "Sabotage" modes.
