Buddy System explained
The Buddy System proximity chat is crafted to provide realistic in-game audio feedback based on player movement and position. As players get closer, their voices appear clean and uninterrupted. Moving further apart results in voices transitioning to a radio-like sound with increasing distortion and eventual cutoff at a specific range. The system also accounts for audio directionality, ensuring teammates' voices reflect their position relative to you, adding deeper immersion and situational awareness during gameplay.
Using emotes for communication
Emotes offer a quick way to communicate non-verbally in multiplayer sessions. Here’s how to use the emote system:
steps
- Access the radial emote menu while in the game.
- Choose from expressive gestures such as thumbs up, clap, or frustrated.
- Use emotes strategically alongside voice chat to increase communication efficiency.
