This month’s update includes the release of the Naga, 'mech adjustments,, quirk adjustments, and more!
As always, a 2 week in-game Patch Science Sale will go live shortly after the patch and include all applicable items for testing.
'Mechs in-game and new 'mechs releasing are subject to future balance changes and tuning, so get out there and do the science so we can hear your feedback!

Naga

The Naga is here, and with it comes the Arrow IV! The Arrow IV is a locked extreme range artillery missile exclusive to the Naga (in March we will be releasing a booster pack of Railgun and Arrow IV variants that will eventually release for C-Bills in game).

Note for NGA-PRIME and NGA-B: TAG range is capped by the mech sensor range. If your mech sensor range is 1200m but your TAG range is 1500m, your TAG will not function outside of 1200m.

Arrow IV stats:

• Slots: 8 (we have reduced the slot count significantly to make the weapon compatible with future variants, as crit splitting does not exist in MWO)

• Tons: 12 (Inner Sphere is 15... when it happens)

• Weapon Health: 25

• Missile Health: 20

• Damage: 10 pinpoint + 10 splash in each adjacent component

• Heat: 8

• Cooldown: 5

• Velocity: 200

• Minimum Range: 180 (0 damage)

• Maximum Range: 1500

• Ammo per ton: 6

• Arc behavior: The maximum height of the indirect arc is slightly higher than LRMs, however that scales with distance. When firing at moderate ranges, expect them to behave similarly to LRMs while arcing high at extreme ranges. They will not arc similarly to the Arrow IV weapons in Clans. This weapon can be dumb fired.

Weapon Changes

• Increased Inner Sphere AC2 optimal/max range to 810/1620 (from 720/1440)

• Modified Clan LBx5 optimal/max range to 620/1550 (from 720/1440)

Smaller LBx cannons have become significantly stronger after the November 2025 patch, although LBx 5 had a slight nerf in the December 2025 patch.. To help lean more into the shotgun aesthetic, the maximum range on Inner Sphere LBx 2s and 5s are now 2.5x instead of 3.0x. To create parity, Clan LBx 2s and 5s have had their maximum range increased from 2.0x to 2.5x.

• Increased Light AC2 optimal/max range to 660/1320 (from 540/1080)

• Reduced Light AC2 cooldown to 0.75 (from 0.9)

• Reduced Light AC5 shell count to 1 (from 2)

• Reduced Light AC5 ammo per ton to 40 (from 80)

• Removed Rocket Launcher 10/15/20 minimum range

• Increased Rocket Launcher 10/15/20 velocity to 500 (from 420)

• Reduced Rocket Launcher 10/15/20 damage to 0.375 (from 1)

• Increased Rocket Launcher 10 ammo to 127 (from 48)

• Reduced Rocket Launcher 10 heat to 0.094 (from 0.38)

• Removed Rocket Launcher 10 ghost heat

• Increased Rocket Launcher 15 ammo to 127 (from 96)

• Reduced Rocket Launcher 15 heat to 0.188 (from 0.38)

• Increased Rocket Launcher 15 ghost heat limit to 3 (from 2)

• Increased Rocket Launcher 15 projectiles per fire to 2 (from 1)

• Each fire will still consume 1 ammo despite multiple projectiles, similar to LBx

• Reduced Rocket Launcher 20 heat to 0.282 (from 0.38)

• Increased Rocket Launcher 20 projectiles per fire to 3 (from 1)

• Each fire will still consume 1 ammo despite multiple projectiles, similar to LBx

We feel that the Rocket Launcher rework pushed them in a better direction from a design standpoint but still had some major issues. The first was that larger Rocket Launchers lasted longer, meaning that mix and matching sizes wasn’t an option. With this change, all Rocket Launchers have the same longevity. The damage reduction and rate of fire increase helps gear them towards more saturation weapons. The second issue was that they were too intensive for what were supposed to be supplementary weapons. There are only a few mechs that could carry a large array of Rocket Launchers as their primary weapon, but the design is intended to be a lightweight supplementary weapon for mechs that have spare tonnage in their loadouts.
