Greetings MechWarriors!

It's the last patch of another year of MechWarrior Online, and what a year it has been! 2021 saw the first new content added to MWO in years, including new 'Mech variant packs like the Stryker, Warden and Hunter Booster Packs, and re-balanced maps like Canyon Network and Viridian Bog, with some having extensive overhauls such as Polar Highlands and HPG Manifold. Speaking of new 'Mech variants and new maps...the Predator Booster Pack is available now for Pre-Order and arrives next month. Then there's maps. Specifically, this month's map, Hellebore Outpost. Based on the biome from the Faction Play map Hellebore Springs, Outpost was designed from the ground-up by Francois, and represents the first completely new map to MWO in years. This will be a Quick Play map, and there are lots of previews below. We hope you enjoy it!

January is right around the corner, and with that will come another patch, and more news about the future of MechWarrior Online in 2022!

As with everything, these updates are subject to further balance changes in the future, especially as more variables are brought into the equation with future updates and changes.

So get out there and do the science, and get us your feedback for future iterations!

Happy Holidays MechWarriors!

And now, we hope you enjoy the patch.

-The MechWarrior Online Team


NEW MAP: HELLEBORE OUTPOST
Hellebore Outpost is a new Quick Play map, based on the biome from the Faction Play map Hellebore Springs. Outpost was designed from the ground-up by Francois, and represents the first completely new map to MWO in years.


















WEAPON ADJUSTMENT
As a continuation of our assessment of weapon performance, the following change has been made:

Clan ER Large Laser:
  • Heat increased to 10 (from 9.5)


EQUIPMENT ADJUSTMENT
This patch includes a small boost to the dissipation performance of single heat sinks. The aim for this change is to make single heat sinks into valid options for number of mechs and build configurations.

Single Heat Sink:
  • Dissipation increased to -0.15 heat per second (from -0.14)
  • Heat capacity increased to 0.85 per external single heat sink (from 0.75) *
Note: the initial 10 single heatsinks on a mech provide 2.25 capacity (including both external and engine)

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): - http://patcher.mwomercs.com/patch/Production/frontend/FrontendPatch_395.zip

  • 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
