Thank you for playing BATTLETECH! We appreciate your patience and support as our team works to quickly investigate and address reported issues with the game. Release 1.0.3 is now available for all users on Steam and GOG. It will be available for Paradox Launcher and other platforms on 5/16/2018.

We have also noticed a high rate of Steam client game update failure lately, and Valve has advised If you have difficulties with the Steam client recognizing the update or updating properly, you should opt-in to the Steam client beta for a newer version with a potential fix. This can be found under Steam->Settings->Account. Even then, you may need to “verify integrity of game files…”, restart the Steam client, or even restart your computer. This extra caution and attention will ensure that the BATTLETECH 1.0.3 update has been properly applied.

Players with nVidia graphics cards should now update to the latest nVidia driver and not use the BT game ready driver that was released at launch.

As always, if you experience further issues please contact Customer Support at: https://support.paradoxplaza.com


Release 1.0.3 Notes, 5/15/2018

Fixed some hitches when destroying units and buildings during combat.
Memory management improvements around 'Mech destruction.
Fixed an issue that could cause MechWarriors to become permanently stuck in the High Spirits or Low Spirits state.
Fixed an issue where saving the game immediately after salvaging enough parts to complete a new 'Mech could cause that new 'Mech to disappear upon reloading that save game.
Fixed an issue that could cause allied units in Escort missions to fail to move into the extraction zone under certain circumstances.
Fixed an issue where choosing to store a 'Mech with an active work order, then cancelling the warning popup, would cause the screen to become unresponsive.
Fixed a few issues with starting location spawn points on procedural missions.
Fixed hair shader to better support brighter colors in character creation, tweaked some hair and beard textures, and added some brighter color swatches.
Added new portrait presets and customization options.
Fixed an issue that prevented completion of the "Rock 'Em" and "Sock 'Em" achievements.
Fixed an issue that could prevent completion of the "Complete Roster" achievement.
Fixed an issue that trivialized completion of the "Laser Show", "Bullet Farmer", and "Raining Fire" achievements.
[STEAM] Added a warning popup that appears if the Steam API fails to initialize on game start.
Added text to the video settings screen to indicate that some settings will not be applied until the next game load.
Added an option in video settings menu to show unsupported display resolutions (defaults to off).
[macOS] Support for non-standard Steam install directories (directory paths with special characters like "=" in them.)
Fixed artifacting issues present on a subset of "Mercenary MechWarrior" custom Backer Emblem rewards.
Made the Backer Atlas "SBA" prefab available for the Atlas II-HT (in addition to being available for the standard Atlas AS7-D.) Made the Shadow Hawk "Umbra" prefab available for the Shadow Hawk 2H. Made "Valhalla" prefabs available for their respective chassis variants.
[SKIRMISH] Alternate prefab 'Mechs are now considered stock, and display in the Stock 'Mechs list in Skirmish Lance Config.
[SKIRMISH] Copying an alternate prefab 'Mech now correctly preserves the 'Mechs variant appearance.

Our troubleshooting launcher remains on the public_beta branch. If you are having trouble running the game and have not yet opted in to the public_beta branch, please do so in order to have access to additional configuration options that may help you:

[WINDOWS] [STEAM] [GOG] Added an optional BATTLETECH Launcher that can be used to configure the following options before launching the game: Borderless Windowed Mode, Exclusive Fullscreen Mode, Video Rendering API. We recommend using these options for troubleshooting if you are experiencing hardware or software compatibility issues. To use this launcher, run the BattleTechLauncher.exe in your installation folder. In GOG Galaxy, you can open the More menu next to the Play button and choose Other -> Configure BATTLETECH.

Additional note for players who mod various game files...Reminder that modding is not officially supported. If you have saved a game with any mod active, that saved game will not work after an update has been applied unless you replace all modded files exactly as they were when the save game file was created. Saved games require the exact same data state in order to function properly.

Stuttering seems to be a bit worse, and couple that with the load times and I feel like my 16GB DDR4, GTX980TI rig is no better than a console. I don't think the game is so spectacularly detailed to warrant that kind of performance.

I've noticed that when you have high pilot skill and choose to shoot then move, there is no vision cone when choosing what direction to look. There has also been instances in the Mech Lab where my Mech was slated as Under Tonnage because if I added 1 more tick of armor, he'd be 60.01/60 Tons. Seems like a rounding issue. Also, during the intro screen, it says PRESS ESC TO SKIP a good 2 seconds before it respects the button press to skip. (And on that note, the game seems inconsistent with what cinematics you can skip - I can skip my ship docking with a Jump ship, but not the undocking sequence?) Personally, I'm not a fan of the UI that indicates your weapons effective reach. I think when moving the cursor, weapon names should have an icon by them that changes color. Gray means out of range, green means optimal rnage, yellow means suboptimal (too close/far) and red means the weapon is in range, but due to the current facing direction, it cannot be fired. This would all work with the enemy you've right clicked as your imminent target.

Keep up the great work. The game is super fun!

That's because you have no weapons able to fire to display cones for. There's a needle right on the circle that points where you're facing.

But there are facing cones (for convenience, one assumes) even when you are not in combat. Facing is critical in this game. It is a shame that they make you guess about it, in some cases.

It works fine for many others. It might just be a corruption of some kind in your installation. This can happen during the download process or because of some modding being incompatible with the new patch. Try verifying files.

You can try changing display resolution. You can also get tech support using links from the stickied thread.

Updated yesterday from "1 day after release version" to 1.0.3-280R.

Some Loadtimes are shorter.
Game runs stable, as it did before.

Any word of an OSX installer for 1.0.3? Gog download still shows the previous 1.0.2 one.
