Hot Fix: The reference for the Mercury F2 dev-tool cameras used to create some scenes for the launch trailers has been removed. Calling it would cause a recursive stack overflow exception as some of these dev-tool cameras was missing. This would lead to a CTD. I plan to re-introduce these cameras with some additional orbiting cameras in a later patch.

Thanks for reporting, as this is a crash that can ruin a long mission flow by accident I wanted to roll out a hot fix for this to correct the behavior as fast as possible.

Note: If this patch causes new issues for you, please report them. You can always revert back to a previous version using the Steam Betas tab for the game. The latest previous version is: 1.0.7.

Thank you for reporting!

The 1.0 bits of Reentry - A Space Flight Simulator has ascended into orbit, and the launch so far has been filled with joy, anxiety, stress and excitement, all at the same time. I would not have managed this without your great support so I want to start by saying THANK YOU to all of you who have been part of this, and for supporting me with this project in any way.

I have been busy this week trying to capture gameplay reports, issues and bugs. I have tried to read every message posted in the community, suggestions, feedback, and I have been following various streams from players playing the game to take note of various issues and struggles they occur.

After the 1.0 bits went live last Friday, all development time has been focused on solving launch-day issues, bugs, and make improvements based on these experience reports I have seen. I will remain in this mode until version 1.1 is released.

Note: If this patch causes new issues for you, please report them. You can always revert back to a previous version using the Steam Betas tab for the game. The latest previous version is: 1.0.6.

Maneuvering in the Cockpit: Look Around

One of the key gameplay areas is to sit inside the cockpit. Some players want to change the default button used to Look Around inside the cockpit from the middle mouse button to something else. This is fully supported and a frequent re-bind I see is to use SPACE for this. Some also changes the Left and Right Trigger buttons (those used to flip switches).

I have made some improvements to this system and fixed an issue where if you bind the Look Around key to become the Left Mouse Button (LMB), it will conflict with the UI interaction system, preventing any UI interaction while in-game. Binding it to the Left Mouse Button is not recommended, but should now be better supported if required.

Note: A known issue I still need to solve related to this particular scenario where someone needs to use LMB to Look Around is to avoid moving the camera rotate while dragging UI elements.

You can also bind a key to toggle the Look Around mode. This will let you look around without having to continuously depress & hold a button and instead just toggle it on or off.

Maneuvering in the Cockpit: The Mercury attitude control stick is in the way in F7 view

Another issue I have seen quite a few reports on is that the Mercury attitude control stick is in the way when pressing F7 to snap the camera to the comms-panel. I have fixed the attitude stick, moved it back to where it should have been. This fix is mostly relevant to those who used the camera snapping system as opposed to moving it around manually using the FPS mode and arrow keys.

Maneuvering in the Cockpit: Cockpit Bounds changes

Another improvement I have been working on is to better detect where the cockpit bounds are. This patch rolls out the first iteration of an attempt to improve this. When the camera leaves the cockpit bounds, a black warning message fades in and shows you this.

This patch makes the boundaries much tighter, and adds a new Realism Setting that can automatically stop the camera if it tries to leave these bounds.

Questions for you: If you toggle the new setting, I will still show the "Out of bounds" warning if you try to continue to move in the direction when the camera stops. Would you like me to remove this? Currently it is a hard stop, and I am curious if you want it to bounce off/glide along the main movement direction instead?

Mission Fixes

I have continued to iterate on various missions where I have fixed mission text, corrected reported typos and fixed small issues seen on various streams. This includes mission flow and for example updating the default values of the Apollo Campaign 3 and Campaign 4 TLI burn planner parameters.

Lunar Module legs snaps on landing

I have made a fix for an issue where the Lunar Landing evaluation could potentially become wrong if you performed more than one lunar landing in the same session (without exiting the game in-between).

Mission Accomplished

Various factors can complete a mission, such as splashing down or completing mission instructions. When the mission completes the "Mission Accomplished" screen will automatically pop up. You can disable the automatic popup of this screen in Realism Settings.

I have made it possible to interact with UI elements such as the Mission Comms box etc. through this screens background.

You can always press RESUME SESSION to close it, continue with the mission and then end it manually from the ESC-menu.

Star Identification toggle

One key thing during any Apollo mission is to navigate using the stars. During Apollo missions, you will become better and better at learning the star and how they map the "sky". The game comes with the star map used during the Apollo program. It is accessible from the Mission Pad and can be used to study and navigate during a mission.

While looking through the scope, you will be able to see various stars, and some of these have a blue halo around them to help you visualize a star that also exists in the Apollo Guidance Computer memory.

Based on requests I have now rolled out a toggle that lets you disable these Star Identification helpers.

Note: By disabling this Realism Setting, Apollo missions will become much harder. I recommend disabling this only after you are proficient with the Command Module, and have memorized the star map.

Going forward I will continue working through the list of issues and write fixes for them. Some of them, like improving the Gemini EVA and the weight of the Gemini during this EVA will take a bit of time due to the complexities involved, but stay tuned for the next patch.

Thank you again for your patience and support!

After 10 years of development, Reentry - A Space Flight Simulator is finally out from Early Access!

What a journey it has been. After 7 years of Early Access where I have been in active development with you, the players, the community, and the test pilots, the 1.0 scope has finally been met where the goal was to implement the mandatory systems to allow you to:

• Reach Orbit in Project Mercury

• Rendezvous and Dock in Project Gemini

• Land on the Moon in Project Apollo

The game has slowly evolved to become something much bigger than I ever imagined possible for a single developer. However, I have never felt alone. From the start, you, the community, has joined me along the journey to help me shape the game, support me and been part of the project in one way or another. For that I thank you!

This will be celebrated with the community through a fully online event, and I will be hosting multiple development updates, Ask-Me-Anything's (AMA) and Steam Broadcasts.

THANK YOU!

I want to take this moment to thank you for being part of the game in one way or another, either you reporting issues, sending suggestions, providing constructive feedback, being part of the community, helping out other players, organizing multiplayer sessions, being a moderator, or being a Test Pilot, your work is visible in the game, and can be enjoyed by everyone else. So thank you again!

This patch rolls out some improvements and preparations for crash log handlings, makes some improvements to logging, and exception handling.

In addition it rolls out a minor fix to the Mission Objective UI so it correctly resets after meeting an objective, and improves the Checklist System to detect if you already have the RUN steps of a checklist queued.

Patch notes:

• Improved Cloud Diagnostics support for better crash reporting

• Logging fixes

• Exception handling improvements

• Fix to Mission Objective UI so it resets correctly (could cause confusion)

• Minor Mercury Cockpit model updates

• Fix to the Checklist System so it detects if you have steps from a checklist it wants you to perform already in the queue

• Adjusted some default values for various realism and graphics settings

This update fixes some general stability issues to try and reduce various Crash To Desktop (CTD) cases seen in some reports. Many of the CTD issues has been fixed by updating your drivers, some has been fixed by identifying potential conflicting software, or by reducing graphics settings. I have two dedicated threads about this on the Steam forums, so if you experience various crashes, please check them out and reach out to me.

I also fixed an issue with the Lunar Module Yaw Pulse logic, made fixes to the splash down sound effect used and rolled out quite a few additional fixes to in-game text, missions and dictionaries.

As I have mentioned a few times, now that we are getting close to the release update (1.0.0), you will see an increase in number of smaller patches. The reason for this is that I wish to roll out fixes as fast as possible to ensure they all get additional testing by the Early Access adopters.

I want to specifically thank all of you who have been part of the Early Access part of the game, reporting issues, providing feedback, this helps improve the game for everyone.

Patch notes:

• General core logic stability improvements

• Received crash logs (CTD) where the Unity Image.CrossFadeAlpha function causes a CTD, so I removed all use of this and instead implemented my own function to handle this. This is used on the off-screen switch pointer and orbit view icons.

• Fixed an issue with the LM Yaw Pulse logic

• Water/Splash sound effect fixes

• Mission fixes, typo corrections and dictionary updates

• Fixes to the various virtual cockpit models

• Minor improvements to the logic responsible for the cockpit interactable components such as switches, gauges, fuses, circuit breakers, etc.

The main aspect of this patch (minor) is to roll out various community contributed text improvements and fixes to typos and spelling mistakes. Hundreds of fixes and corrections to various missions, checklists and dictionaries has been applied. Multiple issues in checklists has also been resolved.

It also adds a way to remove the lens flare effect (Realism Settings) and fixes a potential exception in the Mercury Control Center multiplayer module.

Thanks to everyone who has contributed fixes and text suggestions!

Patch notes:

• Community-contributed text improvements

• Fixes to typos

• Mission improvements

• Added a "Disable Lens Flare" realism setting

• Fix in the Mercury Control Center multiplayer avatar handler

This is a minor patch designed to roll out a fix for a breaking Gemini save state issue, and correct an issue where achievements would potentially be unlocked for incomplete campaigns.

In addition, it rolls out the new plume rendering system to the Mercury retrograde engines, rolls out checklist updates, spelling fixes and lesson corrections, fixes an issue where the custom photo 3 in the Command Module wasn't working, and some minor UI corrections.

As we get closer and closer to the 1.0 milestone, I will try to release smaller minor patches that corrects bug fixes, breaking issues and content fixes.

Note: If you experience new issues related to this update, please report them. You can revert back the a previous build using the Steam betas tab for the game. Most recent rollback option: Reentry Version 0.99.90.

Patch notes:

• Breaking: Fixes to the Gemini Save state where the mission cycle timer was incorrectly handled

• Fix for achievements being unlocked for incomplete campaigns

• Use new Plume Renderer in Mercury Retro Engines

• LM Activation checklist fix

• CM: Custom Photo 3 fix

• Typo and Spelling fixes

• Minor UI updates

I have been talking about the journey to 1.0 for many years and, and finally, as you might be aware of, this space flight simulator is about to reach its biggest milestone yet.

The past few months has been focused on improving the game, fixing issues, and rolling out the final few of the 1.0 features. And on November 7 2025, the 1.0 release will roll out and launch.

I recently made a ~10 minute long video about the November launch window, where I talk about expectation settings, the 1.0 scope, and the future of the game. If you have not yet watched this, I recommend you to take a look at it here:

This patch rolls out an engine update from Unity 6.1.9f1 to Unity6.1.17f1 (stability updates and bug fixes related to Unity). It also focuses a lot on Mission and Campaign fixes, text updates, and fixes to reported bugs. In addition, the Mercury Redstone and Mercury Atlas launch areas are improved.

Note: If you experience new issues related to this update, please report them. You can revert back the a previous build using the Steam betas tab for the game. Most recent rollback option: Reentry Version 0.99.90.

Unity Engine upgrade

The Unity Engine upgrade from version 6.1.9f1 (June 24, 2025) to Unity 6.1.17f1 (October 3, 2025) brings the latest fixes, improvements and security updates from a Unity Engine perspective. This should improve stability and fix rendering issues related to the Unity Engine.

This game is a long-term project and will not lock in to a specific Unity version. This will require me to fix potential issues related to engine upgrades and migrations, but should also bring in the latest stability updates to the engine used to run the game.

Mission fixes

A large portion of reported issues, bugs, and typos are related to the in-game content such as Missions and Campaigns. This patch rolls out a lot of these reported fixes and text improvements.

Campaign Completion logic fix

This patch fixes a blocking issue where some players have been unable to receive the completion award/achievement from completing the campaigns.

Gemini Encoder

The Gemini Encoder model has been updated as I wanted to remove the old placeholder model. I still do not yet have a good reference of what the Gemini Encoder actually looked like, so if you know of a photo of it, please share it with me.

PDF versions of the in-game checklists

I have added the community contributed exports of all the available in-game checklists to the Flight Documents pad. Thanks to Icarus for creating these great looking documents.

Launch Area Shadows

I have re-enabled the previously broken shadows while on the pad. I have changed how the launch complex environment works to gain a bit more flexibility on external views, making it a bit easier to work on the external views during pad operations. I have also improved the shaders used to render the launch complex area grounds.

Mercury Launch Complex improvements

The primary focus for version 1.0 is internal cockpit views. However, I wanted to make a slight improvement to the external views during pre-launch.

I’ve applied the launch complex logic improvements mentioned earlier to enhance the appearance of the launch area during Mercury-Redstone and Mercury-Atlas launches. The two vehicles now use more accurate and distinct launch complex models, and I’ve begun incorporating pad details inspired by footage from the real missions.

Mercury Redstone

Mercury Atlas

External view dynamic shadowing logic (Mercury Only)

I have introduced a smarter method to handle shadow rendering in external views. This is out for testing in Mercury and will adjust the local shadow resolution based on the distance to the capsule. This is an attempt to tame the Unity Shadow system for the large and complex scene setup I use to make Reentry - A Space Flight Simulator possible.

Patch notes:

• Unity Engine upgrade from version 6.1.9f1 (June 24, 2025) to Unity 6.1.17f1 (October 3, 2025)
