Greetings MechWarriors!

 This month’s update includes the release of the Icons Booster pack, '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!


 

Loyalty Mechs:

The 2025 Annual Rewards Program has been announced! We are hard at work to get the mechs in a state where we can show a preview. In the meantime, players can check their eligibility HERE!

 

Icons Booster Pack:


Throughout the Clans and the Inner Sphere, there have been mech pilots who have made their prowess known to the world. Whether they have had entire books written for them or just a footnote in a TRO, many of them had their own custom mech variants made. This will be the first of two packs, with the second ones release date TBD. While all of these mechs do have hero names, they will come out for C-Bills after release like other Booster Packs.


Timber Wolf Bounty Hunter 2 TBR-BH2(S)



Shadow Hawk Sandy SHD-5DS(S)



Hellbringer Haight HBR-AH(S)



Dire Wolf Widowmaker DWF-WM(S)



Note from Tiyos: We know this isn’t the configuration of the Widowmaker everyone might recognize. The original Widowmaker loadout is something that can already be achieved with the Dire Wolf omnipod sets in MWO and I wanted to do more than just add an iconic camo spec. So we chose to instead use the “Widowmaker LRM” configuration that she used in her later Trial of Position in 3051.

-- END OF PATCH NOTES --



Patch Files (Direct Download) 

To make the patching process easier for players with limited download caps, we'll be providing direct download links for the patch file(s) that comprise this patch. This will allow you to download the patch file(s) elsewhere, for manual injection into the MWO patcher through a Patch Cache folder.

Aside from allowing you to download the patch file(s) elsewhere, on another connection, there are no additional benefits to performing the patch this way; the patching process itself will be the same.

This direct patch download process will only work for players running the standalone client. It does not apply to players running MWO through Steam.

Patch File(s): TBD
Download the above file(s)
For sake of ease, we recommend creating a dedicated folder for the patch file(s), such as 'MWO Patch Cache'
You do not need to unzip or unpack the patch file(s)
Launch the MWO Portal
Select the three horizontal lines in the top left of the Portal Window
Choose the 'Specify Patch File Cache' option
In the field that appears, paste or enter the location in which you saved the patch file(s) and hit OK
For example, C:\Users\<username>\Documents\MWO Patch Cache
Click the blue Patch button
The launcher will now check the Patch Cache folder you defined. If it locates the required patch files, it will unpack and use those files to apply the patch
Once the patch is complete, launch the game
