Attention Captains,Patch 2.2 is now LIVE!The work on the multiplayer / terminal beta is now complete. This means that you can now assemble a crew of sorts and fly together to uncover the mystery of the Astra Protocol. Will it me a case of many hands make light work, or will it be too many cooks spoil the broth?Here's a summary of all the changes since the last major patch:New FeaturesTerminal SupportThis is the headline feature for this release. We've added in the ability to connect to Astra Protocol 2 via a remote terminal. This is some pretty simple tech at the root of it, so it can be a PC,

Attention Captains,We've uploaded v2.1.4 of the Astra Protocol 2 multiplayer / terminal beta.We believe we're now at the stage where all major features and core functionality are in place. From here, our focus is on tracking down any remaining bugs and ensuring everything runs smoothly.We've even found time to fix another couple of extra issues along the way.Here's a brief summary of some of the changes:New Terminals - Engineering and DockingThese modes now display their intended readouts, giving crew members the information they need.Fixed Modes and CommandsTerminals in fixed modes no longer

Attention Captains,Work continues on the terminal based multiplayer for Astra Protocol 2. We've fixed several major issues, cleaned up a few things, and added some new improvements, which you'll find in version 2.1.3.The game should no longer crash after a failed mission. This was due to the terminal not initialising correctly, and has now been resolved.You can now connect multiple terminals at once. There's no hard limit, though performance will depend on your machine. In theory, you should be able to run a full crew with each member using their own terminal.We've also added fixed modes for t

Attention Captains,This is not an erroneous transmission.The current beta, Astra Protocol 2 (v2.1.1), contains an early prototype of multiplayer functionality - though not the kind you may be expecting.We are experimenting with remote terminal support, allowing a second user to connect to the pilot's machine and issue commands through a terminal interface. The remote player has access to a slightly reduced command set, whilst the primary player retains full control. This opens the door to cooperative roles - perhaps one captain handles weapons whilst the other focuses on evasive manoeuvres?How

Attention Captains,Patch 2.1 of Astra Protocol 2 is now live. This patch brings in a mix of new features and improvements alongside the usual bug fixes. We've added some new exploration options and a few ways of dealing with some tricky situations.Here's all the changes:New FeaturesAchievementsWe've added eighteen brand new achievements to the game - some simple to obtain, others not so much.Speed LimiterNew option to limit the max speed when under the autopilot. Once the ship reaches the desired speed, the engines will stop providing thrust until required to slow down. Controlled via the SET

Attention Captains,We've updated the beta branch to v2.0.5.0. This build should contain all the new features and bug fixes for the v2.1 patch, it just needs further testing and refinement before we release the final version.Here is a summary of the changes in the beta since the last build:New FeaturesAutopilot LimiterYou can activate / deactivate a limiter to set a top speed. Once you reach this speed, the autopilot will stop providing forward thrust, but may still provide lateral or reverse thrust.ImprovementsResupplySpace stations can resupply fighters if you have any that have been destroye

Attention Captains,For those of you trying out the Astra Protocol 2 v2.1 beta, we've just uploaded a new build to it.We've still got a couple more features to implement, as well as all the tweaking and refinement.Key features of the update include:All achievements have been certified as collectable.Fighters, fighter bays, and torpedo tubes can be replaced when destroyed if the space station holds them - this is a resupply action rather than a repair action.The option to toggle 'Safe Havens' around space stations, meaning that enemy ships won't spawn if you are close to a space station - it won

Hi all,We're working on some new features for the v2.1 update and would appreciate some user feedback. As part of this work, we've also updated the executable to be 64-bit, so there might be some knock on compatibility issues, so user feedback is even more vital for us.To allow for this, we've updated the main 'beta' branch to the newest build, v2.0.3. We've not updated any of the documentation yet, but here's a summary of what's included:AchievementsWe've added in 18 player achievements. Most of these have already been checked as being achievable, but we have a couple that we're yet to confir

Attention Captains,We are in a celebratory mood as Astra Protocol 2 has just turned three years old!To celebrate this occasion, we have brought a gift - a new patch!This patch makes some major changes to Astra Protocol 2 as we've brought in a new renderer and framework (those eagle eyed of you might recognise it as the one we've implemented on the Astra Protocol Remake). These changes mean that we can implement visuals that look more like the CRT monitor effect we intended for the original release of the game, allows us to implement some fancy effects, such as distortion from radiation, and ru

Ahoy Captains,We've just uploaded a new build to the beta branch. This update makes a small tweak to how the logging works (which should be invisible to the users) and adds a new experimental feature: Telemetry.Telemetry outputs data for your ship and discovered planets. Users can specify how often the data is outputted and where it sent - so those of you with a dot matrix setup could even output to a printer! This is separate from regular logging, so you send data to different locations simultaneously.The intention behind this feature is to give players more ways to interact with Astra Protoc

Ahoy Captains,Patch 1.8.1 is now live!This patch is a relatively small one which focuses mainly on bug fixes:ImprovementsMaintenance craft slow down sooner, which should limit how often they crash into space stations.Bug FixesFixed issue where player could immediately spawn within a planet.Fixed issue where bad characters in the Captain's Log would crash the game on load.The cursor character no longer gets stored in the Captain's Log (partially responsible for the above crash).Fixed an issue with meshes not displaying properly.We hope that fixing these issues improve your experiences with Astr

Attention Captains, We have uploaded a new beta branch that focuses on controlling Astra Protocol 2 using a gamepad. Whilst Astra Protocol 2 controls best via a keyboard, there are some circumstances where it might not be practical, or possible to use one. This beta intends to get the proposed control system into users' hands so they can help us work out if it is a control system worth pursuing. If all goes well, there's the possibility that it could open the door to a Steam Deck build. If you're still interested, read on. Having a game designed around inputting commands meant that it was a ch

Attention Captains, The upcoming v1.7 patch is currently available in the beta branch. This patch is mainly focusing on some quality of life improvements based on user feedback, featuring new commands, information, and configuration options. Its a relatively small patch compared to some of our other patches, so it may not be too long until it goes live. As usual, please feel free to leave comments here or in the Community Feedback thread - https://steamcommunity.com/app/2026750/discussions/0/5789982181540189847/ Watch this space for further updates
