UPDATE #5: We've discovered a bug in Book One with French/German versions. Look under 'known issues' below for more details.

UPDATE #4: Windows x86 and Linux x64 versions are live — all versions have now been patched to v5.0.3. We're monitoring the forum for any issues that need to be addressed, but so far there's not much. We will probably patch again next week, so please let us know if you encounter any bugs!

UPDATE #3: Mac version (v5.0.3) is now live and 32-bit Windows is next.

UPDATE #2: The game has been patched with v5.0.3, hopefully fixing the save game issue. Please update your clients!

UPDATE: Please read this post before updating the game and starting Book Five: http://steamcommunity.com/app/237850/discussions/0/351659808481827564/

The fifth and final episode of Dreamfall Chapters is now available for 64-bit Windows. 32-bit Windows, Mac and Linux versions are arriving shortly.

With Book Five, you can play the entire story from beginning to end — from Reborn to REDUX — and experience the emotionally brutal (but rewarding!) conclusion to The Longest Journey saga.

Open your Steam client to update the game…and we hope you enjoy the journey's end.

Here are some of the many, many changes and additions v5.0.2 brings to the game.

Change log

• All new episode — REDUX concludes the story of Dreamfall Chapters. There will be tears! But also joy! And laughter! But mostly tears, lots and lots of tears :(
  
• Revamped parts of Book One for clarity and pacing — including the opening chapter in Storytime, with brand new (and hopefully much improved) gameplay
  
• New (and entirely optional, though we recommend using it) Red Thread Games login and cloud synchronisation system — for more information, see below or follow this link: http://redthreadgames.com/forum/topic/696-dreamfall-chapters-faq-known-issues-please-read-before-posting/#cloud
  
• OpenGL 4.1 support on Mac and Linux systems, hopefully resulting in better overall performance
  
• Unity engine update (another one!) from Unity 5.2 to 5.3, with further optimisations to memory management and performance
  
• Improved lighting across multiple scenes from previous episodes — including Friar's Keep

Known issues

• EDIT: This is now fixed in v5.0.3. Make sure you update your game before playing. ORIGINAL: Version 5.0.2 has a serious bug that prevents old save games from being loaded. A fix is incoming, and a new version should be available very soon. No save games have been corrupted or deleted
  
• EDIT: There is a known issue with German and French versions when playing Book One. After Baruti's confrontation with Mr London, French/German players are unable to complete the goal and progress in the game. A workaround is to temporarily switch to English language when playing this scene, and going back to French/German after. We apologise for the inconvenience, and we will patch this shortly
  
• Light shafts (god-rays) shader issues on OpenGL systems (Mac/Linux), resulting in no light shafts being rendered on these systems. We're working on a fix and we hope to have a solution soon
  
• German and French subtitles are missing for Book Five. We will be patching those in as soon as they arrive
  
• German voice-overs for Book Four and Five will be added soon after release — we will provide more details as soon as possible

New cloud login and synchronisation system

We've added a system that keep tracks of your progress between installations of the game — and across platforms. This means you can carry over progress from PC to consoles and mobile platforms, and vice versa.

When you first start up the game after updating to Book Five, you will be prompted with a registration window. By entering your email address — and clicking the verification link we send you — your unique client ID (unique for every installation of the game) will be connected to your account created in our database.

Since your account is connected directly to your email address, and new client registrations have to be verified via that email, we do not require a password for your account.

Once you've successfully logged in, your email address will be displayed in the top-right corner of the title screen. If you're not logged in, you will see a message like 'Login' or 'Verification pending' (dependent on current status) in the top-right corner. You can re-open the login window by clicking your email address/status message at any time.

For every new device/clean install of the game, you will have to log in and verify that specific client for it to be connected to your account.

Connecting to this service will ensure that your progress will be synchronised to our servers, and you will have the ability to download your progress to any other device that is connected to the same account. The only data uploaded to our servers are your latest saved game and the decisions you've made up until that point in the story.

As the game starts, the data connected to your account, stored on our servers, is compared with the data stored locally on your computer. If a more recent set of data is located on the server, you will be prompted with the synchronisation window on the title screen. Here you will have the option to download your most recent progress from our servers. You can also to skip this step, and continue without synchronising.

Once you select the synchronize option, the data stored on the server will be downloaded and placed locally on your machine. Now you can continue the story from where you previously left off, regardless of platform.

Rest assured that no data will be overwritten or deleted during this process. It is simply copied from our servers and downloaded to your system.

Your email address will never be shared with third parties or used for any other purpose than maintaining your Red Thread Games account.
