Greetings MechWarriors,

Read on for all the details of this October patch, and we'll see you on the battlefield!

As a final note, when compared against our previous patches over the last year this October patch features relatively fewer fixes and changes for 'Mechs and Maps. For these patch notes we have opted to collect the majority of fixes and changes into the single 'Other Fixes and Changes' section.

Rounding out the patch we have a comprehensive optimization pass for connecting, loading, and performing actions within MechLab, an array of new Cockpit Items for purchase, a set of 23 new Decals with which to customize your 'Mechs, and much more.

The Art team continues their work on Pattern retrofits for the remaining 'Mechs without full Pattern Support. In this patch all variants of the Blackjack, Firestarter, Highlander, JagerMech, Quickdraw, and Victor 'Mechs now have full Pattern support.

The content featured as part of the 2016 Appreciation Program is releasing in this patch to all eligible MechWarriors! We greatly appreciate your support over the last year, and we very much hope you'll enjoy this bonus content.

Terra Therma is the latest map to undergo a design and beautification pass. The changes to Terra Therma are significant; while the name remains, Terra Therma is almost entirely a new map and experience.

The Huntsman has arrived, and is now en-route to the MechBays of eligible MechWarriors. While the Huntsman traveled a circuitous route to creation, it has amply filled the original vision that inspired its design. Its excellent balance of speed, armor, and firepower has made the Huntsman a highly-regarded and extremely potent Medium OmniMech, prized for its flexibility against a wide range of opponents and battlefield conditions.

The HMN-PA is the Hero variant of the Huntsman, featuring a unique Hero Pattern and a 30% boost to C-Bill earnings. Until its release date for in-game purchase the HMN-PA is only available as a Hero Add-On to an existing Standard or Collector Huntsman Pack.

Until its release date for in-game purchase the HMN-P is only available as a Reinforcement Add-On to an existing Standard or Collector Huntsman Pack.

Until its release date for in-game purchase the HMN-C is only available as a Reinforcement Add-On to an existing Standard or Collector Huntsman Pack.

Until its release date for in-game purchase the HMN-B is only available through the Standard or Collector Huntsman Pack.

Until its release date for in-game purchase the HMN-A is only available through the Standard or Collector Huntsman Pack.

The HMN-Prime is the standard version of the HMN-Prime [S]. It does not possess the 30% C-Bill boost or the unique Pattern of its [S] counterpart. Until its release date for in-game purchase the standard HMN-Prime is only available through the Standard Huntsman Pack.

The HMN-Prime [S] is a Special version of the HMN-Prime, featuring a unique Pattern and a 30% boost to C-Bill earnings. The HMN-Prime [S] is only available through the Collector Huntsman Pack, and will not be made available for purchase in-game.

• 'Mech/Weapon Slot(s): 1 (only available after unlocking that variant's Mastery Skill tier)

As the last of the 'original' maps to undergo a modernization and update pass, Terra Therma has fittingly undergone a complete redesign at nearly every level. Therma has always been one of the more divisive maps in MechWarrior Online; while the elevated heat levels alone are a deterrent for some, the previous layout and design of the map, with its single, centrally-located caldera, weren't conducive to promoting a diversity of gameplay options. Our primary focus of this redux was to address the most common complaints and issues with the previous Terra Therma, and the result of these changes has transformed Terra Therma into an entirely new map.

The central area of the map, previously home to the relatively high-elevation caldera in the original map, is no longer the focal point of Terra Therma; there are now four primary areas of engagement in which players will be likely to meet in combat. These areas are spread throughout Terra Therma, with clearly defined pathways, landmarks, and cover to help guide the action and provide players with multiple opportunities for their approach.

Other Additions • An array of effects and map features, such as fire twisters, ashes and embers, sporadic volcanic rock ejecta, and lava formations • Dynamic lighting cycle

The system that manages communication between the MechWarrior Online servers and your MechWarrior Online client has undergone an extensive technical overhaul in this patch.

These improvements follow in the steps of previous improvements to the system for Saving changes to your 'Mechs seen in the July 19 patch, and are similarly geared toward improving fundamental components of the MechLab. Additionally, these improvements should further help to improve connection times when returning to MechLab from a match or Testing Grounds session; an increase to those connection times came in with the improvements to Saving, and we have been working to bring them back to acceptable levels.

Every aspect of the MechLab that involves some action will see a reduction in the amount of time it takes for the client to process that action. For some scenarios the changes will be drastic; for others, much less noticeable. The degree to which you may perceive these improvements will also depend on personal factors such as your connection speed and the amount of content in your MWO account. That said, on average, we expect these various optimizations to be noticeable to a large portion of the active playerbase. Under the previous system, purchasing a single 'Mech through the in-game store could take upward of 15 seconds to fully complete, even when running on a fast connection. With these optimizations in place, the same action under the same configuration now takes a second or two at most.

• Entering MechLab, both for the first time of the initial login, along with returning to it from a match or Testing Grounds session should be significantly faster. • Purchase actions such as buying a Weapon, 'Mech, MechBay, or any other purchasable item should be much faster, with a reduced need for the 'Refreshing Data' process. • Similar improvements should be seen with saving changes to a 'Mech and unlocking Supply Caches.

Known Bugs and Issues potentially addressed with these Optimizations:

• MechLab: Fixed an issue where Disconnecting from an active Match could cause the visual In-Game flag to not be present on the 'Mech. • MechLab: Fixed an issue where an item that had been removed from a 'Mech could fail to appear back in the Warehouse Inventory until the client had been reloaded. • P rivate Lobby: Fixed an issue where the 'Searching' alert would sometimes not display for a player if they were attempting to purchase an item. • Skills: Fixed an issue where players could get stuck with the 'Unlocking' message. • Skills: Fixed an issue where 'Mechs could lose already unlocked Basic Tier Skills after being sold back. • Social Window: Fixed an issue where the Online Status for players in the Social Window could be incorrect. • Store: Fixed an issue where purchasing multiple 'Mechs in a row in could cause the client to be stuck at 'Refreshing Data'. • Unit Chat: Fixed an issue where players who are logging in would trigger a "Player has joined the Unit" text alert. • Unit Chat: Fixed an issue where the MOTD would not appear.

Many of the above issues have been long-standing, and for the most part have proven difficult to replicate in the past. For that reason the above issues are classed as potential fixes; if you see any re-occurrence of the above issues after installing the October patch, please get in touch with our Support services at technical@mwomercs.com.















• Consumables: Fixed an issue where Consumables could be used after your 'Mech had been destroyed. • Faction Play (Scouting > Attackers): Fixed an issue where the DropShip could arrive when first starting the 10th Intel Capture, instead of waiting until the 10th Capture had completed. • Zoom: Fixed an issue where entering Zoom Level 1 could momentarily cause Zoom Level 2 to appear. • Zoom: Fixed an issue where quickly entering Zoom Level 2 could momentarily cause Zoom Level 1 to appear after reaching Zoom Level 2.
