Greetings MechWarriors!

     Today we have a patch with a change for New Players PSR starting point. We hope this will help improve a new player's experience by placing the new player in a tier that reflects their experience level. This is just the beginning of changes coming to MWO that are driven by YOU, the community. We are taking on player feedback and suggestions while mapping a new course for MechWarrior Online 2021! Check out the recent town hall to get a sense of what we will be up to in the new year! 

In the meantime enjoy all the events, sales, and free stuff coming in Winterfest 2020!

The MechWarrior Online Team


  • New Players will start in TIer 5 (900 PSR). 
  • Players who have less than 25 games will have adjustments to their PSR to reflect the new PSR starting point

Bundles - Look for new bundles coming to the Bundles of Joy Sale coming this week in WinterFest.

  • New Mech Bundles.
  • New Item Bundles

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.
