Tsuru Reef Developer Guide Breaks Down the Largest Map
A developer guide walks through Tsuru Reef, the game's 16th and largest map, built for Naval Warfare across six Pacific islands. Principal level designer Richard Starr covers six points of interest — from the Majestic Ikoi Resort to Sunrise Harbor — and how watercraft, shallow-water infantry routes, and destruction shape a round across the chain.
Starr frames the map against Battlefield 4's Paracel Storm, the naval benchmark it builds on.
"Among classic Naval Warfare maps, Paracel Storm from Battlefield 4 stood out as a benchmark" — Richard Starr, Principal Level Designer
Tsuru Reef's points of interest across the island chain Points of interest
Majestic Ikoi Resort — a luxury destination with destructible structures
Mifune Landing — an abandoned art-island revival project
Tsuru Gate — a joint military checkpoint
Tsuru Air Base and Port — military infrastructure with destructible elements
Sunrise Harbor and Moon Shore — a U-shaped harbor built for naval combat
NATO and Pax Armata headquarters anchor the opposing ends of the map
Tactical tips
Island-hop by watercraft to reach objectives across the chain
Move underwater to break line of sight and take shallow routes for cover
Land aircraft in emergencies instead of bailing out
Hold the central island for a positional advantage
Use Mt. Hoshizora as strategic high ground off the objective
Alongside the guide, EA issued a Season 4 launch code, WELCOMES4, good for a 60-minute Hardware XP boost — one redemption per EA account, valid from July 20, 2026, 12:00 UTC to August 4, 2026, 12:00 UTC. It requires Battlefield 6 or REDSEC with all game updates.
