Battlefield 6 Update 1.4.3.0 Brings Season 4, Proximity Chat, and a New Knife

Battlefield 6 update 1.4.3.0 deploys on Tuesday, September 15, with the download window opening at 8:00 UTC across all platforms. Season 4: Tidal Strike content — including the new event, the Phantom Program for REDSEC, and Proximity Chat — goes live four hours later at 12:00 UTC.

What changed

• Deep Six Collection Event runs September 15 through October 12. Players complete contracts and gather intel devices to earn exclusive rewards across Battlefield 6 and REDSEC.
• Diver's Knife — described as originally carried by Royal Navy divers in maritime environments — is the final reward for completing the full Collection Event.
• Proximity Chat arrives in Battlefield Labs for Live. Voices are placed directionally and shaped by the surrounding environment; walls can obstruct them, indoor spaces alter their quality, and being inside a vehicle affects what is audible. Players can see who is speaking, with options to mute or report. Solo players and parties default to Game voice chat.
• The update also includes quality-of-life changes, balance updates, and bug fixes, though the source text is truncated before detailing them fully.
• A quick channel-swap shortcut has been added below the Commo Rose.

For players who have found large-scale matches impersonal, Proximity Chat's directional, environment-aware audio represents a structural shift in how strangers interact on the battlefield.
