Game Update 1.3.1.0 is one of the largest patches Battlefield 6 has seen since launch, and Battlefield Studios dropped the full patch notes on May 8 ahead of Season 3's May 12 release. Beyond the new Railway to Golmud map, three weapons, and Ranked Battle Royale Quads, the update delivers a broad sweep of fixes and rebalances that touch almost every system in the game.
How vehicles are changing in Season 3
Vehicles get the most significant treatment in this update. The angle damage model on tanks has been simplified so incoming damage is easier to read: turret hits always deal 75% damage, body hits deal at least 100%, side hits at a favorable angle deal 150%, and rear hits at a favorable angle deal 200%. Previously, extreme damage spikes at the rear were compressing the time-to-kill into an unpredictable range. This change tightens that window considerably.
The regeneration system has also been reworked. The critical health bracket no longer stops regen entirely; instead it slows it by 80%. Regen delay doubles from 6 to 12 seconds, but the rate increases from roughly 5% per second to 10% per second, and vehicles now regenerate all the way to full health rather than stopping at the next bracket.
Tracked vehicles get a new transmission and steering system for smoother acceleration and tighter turns. Tanks are no longer immobilized by high damage hits (anti-tank mines still immobilize them), and the boost bar no longer empties when you interrupt a boost mid-use.
MBT health increases to 1200 while APT health drops to 800. Weapon damage values across the M1A2 SEPv3, Leo A4, M3A3 Bradley, and Strf 09 A4 have all been retuned, with IFV cannon reload times increasing from 2.4 to 2.75 seconds and APDS round rate of fire dropping from 200 to 120 RPM. If you want a detailed breakdown of how each vehicle class plays with these changes, the Battlefield 6 vehicles guide covers loadouts and tactics across all eight classes.
The Reinforced Plating passive has been removed entirely and replaced with Contingency Systems, which accelerates countermeasure cooldowns when the vehicle is at low health instead of providing flat damage resistance.
Netcode and combat feedback get cleaned up
Several netcode issues that have been frustrating players since launch are addressed in 1.3.1.0. High-latency players were previously failing to apply armor damage correctly, which meant players on worse connections were at a significant disadvantage in vehicle fights. That is now fixed. Projectiles firing from the wrong height during stance transitions under poor network conditions, which caused legitimate bullet hits to be rejected by the server, have also been corrected.
Hit reactions now move the weapon opposite to the direction of impact when taking damage while aiming down sights. Incoming damage UI indicators animate and scale based on the amount of damage taken, making it easier to distinguish between a graze and a burst that is about to finish you. Bipod animation stuttering on unmount has been fixed, and the issue where first-person hit reactions would trigger even when bullets missed has been resolved.
Gadgets rebalanced around clearer anti-vehicle roles
The RPG now deals 173-460 damage against tanks (up from previous values), and the M136 AT launcher now deals 207-550 against tanks and 1000 against helicopters and jets. Both launchers were underperforming as anti-vehicle tools, and this update is explicitly designed to make them viable again.
The M15 AV Mine gets a damage increase to 390 against tanks, a maximum placement count increase from 6 to 9, and mines no longer despawn 3 minutes after their owner dies. The PTKM-1R Acoustic Mine damage against tanks increases to 480. The MBT-LAW sees its maximum missile speed jump from 75 to 300 m/s and acceleration increase from 50 to 100 m/s, making it far more usable in practice.
The Engineers Supply Crate no longer has limited supply charges in standard multiplayer, allowing indefinite vehicle resupply. The Portable Mortar's shot dispersion has been updated so it is no longer perfectly accurate at maximum range, rewarding closer engagements over long-range spam.
What else is in the update
Automatic weapon recoil has been increased across the board to better define weapon strengths at range, compensating for recoil compensation bug fixes introduced in Game Update 1.2.1.0. Shotguns receive new Speedloader attachment options for the M87A1 and M1014, and the Magnifier is now a shared optic accessory across multiple weapons.
Three new weapons join the roster: the M16A4 assault rifle with burst-fire and fully automatic modes, the L115 bolt-action sniper rifle, and the RPK-74M light machine gun built for sustained pressure at range. The Railway to Golmud map, a reimagining of the Battlefield 4 classic, is described as the largest map in Battlefield 6 to date, featuring a moving railway that squads must fight to control.
Seasonal Statistics have been added to the Player Profile, separating seasonal performance from lifetime totals. The update also adds support for AMD FSR 4.1, Intel XeSS 3.0 with 3x and 4x Multi Frame Generation, and PlayStation Spectral Super Resolution 2 on PS5 Pro.
