Quick Links

Greetings MechWarriors, and Happy New Year!

The Piranha 'Mech has arrived, and is now en-route to the MechBays of eligible MechWarriors!

This patch sees a handful of gameplay-related adjustments, including Quirk changes for the Assassin and Shadow Hawk 'Mechs, improvements for the Light and Heavy Gauss Rifles, and more.

Rounding out the patch we have a number of fixes and improvements for maps, 'Mechs, and the frontend, the release of standard, purchasable versions of the 2017 Rewards Program Cockpit Items, the release of reward items for MWOWC Finalists, Qualifiers, and Participants, and more.

Read on for all the details, and we'll see you on the battlefield!

-The MechWarrior Team

MC Release Date: June 5th 2018
C-Bill Release Date: July 3rd 2018

You can check out the Quirk information for the Piranha as part of our Countdown post here.

The Piranha also brings with it 3 new Colours for purchase with MC in-game. Early Adopters of a Piranha Pack receive these colours for free.

Heat Gen Nodes

IS and Clan Heat Gen Nodes now have separate values in the Firepower Tree.

Inner Sphere values remain unchanged.

• -0.75% per Node.
• -10.5% total.

Clan values have been adjusted to the following:

• -0.6% per Node (down from -0.75%).
• -8.4% total.

Heat Gen Design Notes: After reviewing the net benefit provided by the Heat Gen Nodes within the Firepower Tree, we have determined that the original values were providing inflated benefits on the Clan side compared to the benefits offered for IS 'Mechs. This change is therefore aimed at bringing the net benefits between the two factions closer in line, accounting for a typical Clan Loadout and a typical Inner Sphere Loadout.

Light Gauss Rifle

• Cooldown reduced to 2.6 (from 3.25).
• Heat reduced to 0.55 (from 1).

Light Gauss Rifle Design Notes: The Gauss Rifle family of weaponry is designed around high Damage for minimal Heat at relatively long ranges, with the Light Gauss' primary features revolving around its long range and its very fast projectile speed. With this patch, we have provided the Light Gauss with a moderate boost in overall DPS to provide it better value considering the weight of the weapon, without overlapping its role with similarly weighted weapons. We have also reduced its Heat. While this may seem superfluous given its already low Heat value, with the added DPS we found the weapon was causing just enough Heat to stall out of the dissipation of Heat reserves for weaponry paired with the Light Gauss. As minimal Heat is at the heart of its niche, this behavior was not providing us with the intended benefit of supporting supplemental weapons paired with this rifle, and therefore necessitated a reduction in its Heat.

Heavy Gauss Rifle

• Optimal Range increased to 220 (from 180).

Heavy Gauss Rifle Design Notes: This change is the result of direct feedback from 2017 MWOWC finalists, and is intended simply to push out the effective range of the Heavy Gauss Rifle.

Clan Medium Pulse Laser

• Max Range reduced to 480 (from 561).

Clan Medium Pulse Laser Design Notes: Due to the 50% extra Optimal Range over the IS Medium Pulse Laser, the Max Range of the Clan Medium Pulse Laser extended to a point where it was being utilized in ways that we felt made the weapon too much of a generalist compared to its IS counterpart. The Max Range has therefore been reduced to a point where there is much closer parity between the two weapons in terms of Max Range. However, the Clans will continue to possess superior Optimal Range and Damage.


• Cooldown increased to 5 (from 4.5).

Clan ER PPC Design Notes: While we are satisfied with the ER PPCs effectiveness in ranged combat, this change is intended to provide a slightly longer window over which closer-ranged opponents can attempt to pressure Clan ER PPC carriers when they are caught out of position.

Only two 'Mechs are receiving Quirk adjustments in this patch. As a result, we have not provided the usual PDF document. The changes will simply be outlined here.


• ASN-21 Armor Quirks have been converted into Structure Quirks.

Assassin Design Notes: The Assassin chassis as a whole has carried through a number of heavy Quirk benefits from its pre-Skill Tree state, and has slowly compounded on those changes as we continue to work toward improved baseline tech balance. While many variants of the Assassin have remained on-target, the ASN-21 has been consistently punching above its weight to the detriment of many 'Mechs that occupy a similar niche in other weight classes. While we're issuing only a minor change to its Quirks in this patch, we will consider further changes if the 'Mech continues to push out many other 'Mechs occupying similar, SRM-focused roles.

Shadow Hawk

• SHD-2D has received a -5% Missile Spread Quirk.
• SHD-2D now has a +10 Structure Bonus for the Left Arm and Right Arm (up from 5).
• SHD-2D has received a global -10% Weapon Cooldown Quirk.
With the addition of this global -10% Weapon Cooldown Quirk, the existing Cooldown Quirks have been removed or adjusted:
• -15% Ballistic Cooldown Quirk has been reduced to -5%.
• -10% Energy Cooldown Quirk has been removed.

• SHD-5M has received a global -20% UAC Jam Chance Quirk.
With the addition of this global -20% UAC Jam Chance Quirk, the existing -20% UAC5 Jam Chance Quirk has been removed.
• SHD-5M has received a global -10% Weapon Cooldown Quirk.
With the addition of this global -10% Weapon Cooldown Quirk, the following Cooldown Quirks have been removed:
• -10% Ballistic Cooldown Quirk has been removed.
• -10% Energy Cooldown Quirk has been removed.
• The -10% UAC5 Cooldown Quirk remains.

• SHD-2H/SHD-2H [C]/SHD-2H [P] have received a -10% Laser Duration Quirk.
• SHD-2H/SHD-2H [C]/SHD-2H [P] have received a global -15% Weapon Cooldown Quirk.
With the addition of this global -15% Weapon Cooldown Quirk, the existing -15% Ballistic Cooldown Quirk has been removed.
