I have never played this game, but I know one thing. If someone installs a speaker for you on the battlefield, they probably don’t want to kill you. If the enemy doesn’t talk nonsense, they will just come up and kill you. .

You should point your gun at him and be ready to attack at any time to see if he makes any move. If you dare to take action, kill him first. If you want to join forces, get in the car and fight with him. After all, there is strength in numbers. Even pig teammates can waste the enemy's bullets.
