The Battlefield 6 1.4.1.0 patch notes open Season 4: Naval Warfare with its Pacific Front phase, led by Tsuru Reef — the largest map in Battlefield 6 history — and the game's first dedicated naval combat with the RCB-90 Patrol Boat and NSW RHIB. Track the live Battlefield 6 season countdown through Naval Warfare.
TL;DR — Phase 1 content drop: 1 new map (Tsuru Reef), 2 new naval vehicles, 3 new weapons, 2 new attachments. Meta impact: combat opens up across land, sea, and air on Tsuru Reef, with a Dynamic Wave System changing boat handling and mounted-weapon aiming mid-match.
