- v0.3.0 - Almost There - 27 July 2026
Hello, just wanted to drop a quick update on where the game is at. Aside from the factions update, I wanted to improve a lot of the groundwork for the game and fix some bugs. I know it can be frustrating for development to stretch out longer than expected, but I want to make sure the game is solid when it reaches you. Thank you so much for sticking around, and for being patient with the development.(Scroll all the way to the bottom to see some of the new stuff!)The following features will be available once the upcoming v0.3.0 update releases:=== TL;DR / Main updates ===STRATEGIC- Better factions - Bounties now affect relations with other factions - Factions have different demographics and ideologies, which factor into their government representatives, which vote for decisions during events - Events: Random (like station workers striking), Cause (voted for by government, like tariffs or…
- v0.3.0 - In Progress - 6 May 2026
Hello. Thanks for being patient with me. I wanted to make sure I get a lot of things done and concrete before I talk about the progress I've been making on v0.3.0. There have already been a lot of fixes on things like UI scroll affecting the camera and decal visibility range being too short. I also managed to add in nameplates and flags for ships in the Tactical Scene, to make the ships feel like they actually belong to a faction.Just a bit of info about what the factions update will look like:- Factions have a system of government with representatives and demographics- The three government types are: dictatorship, oligarchy, and republic- A faction's representatives will vote on spending, policies, diplomacy, and how the faction would react in certain events- The player will be a representative at the start and can pay for an election campaign at the end of their term to become a repre…
- v0.2.4.1 - 5 April 2026
Whoops! I forgot to add a fix to the below bug. I knew there was something missing in the v0.2.4 changelog! FIX - Tutorials 1 and 3 + Tactical: Repairing a module (that has no mounts) keeps using up resource materials even when it's already at full health. This affects repairing the crew module first in tutorial 1 and prevents progression. The technical details if anyone's interested: In the DC cycle, the ship checks if the mounts in a module need to be repaired but I overlooked that if a module has no mounts, it always returns "0" (for the module's 'mount health ratio'), which tells the DC cycle that the module needs repairs. This was fixed by adding a simple check to see if the module being repaired has any mounts. *Insert Willem Dafoe facepalm* Just to be safe, I also made the tutorial proceed to the next step if Predawn Blue has no materials left
- v0.2.4 - 5 April 2026
Work on the next major update is in full swing! I'm very excited for what I got cooking up. In the plans, I have: events (both random and faction-based), diplomacy, faction demographics, weekly councils to decide on policies and spending, government types, and more. It's a lot, and implementation and testing will take some time, so expect fewer updates as I focus on the Factions update. This system should be a good stepping stone for what I have planned for Spacefleet: Sol and yes, you will be able to set your faction's government type, vote on policies, and all the rest. But yeah, that's all from me for now. I'm going straight back to work after I post this. I hope you're as excited for this as I am. And as always, happy hunting! NEW - Store Page: Removed screenshot with "Activate Windows" text - Main Menu: Skirmish and new game setup UI buttons sfx - Skirmish Setup: Added map icons -…

- v0.2.3 - Combat Fixes and QoL - 23 March 2026
Hey, gamers! I've been wanting to improve combat for a while now and I finally got some time to work on it this past week. Thanks a bunch for the bug reports with instructions on how to replicate the issue, you know who you guys are. If you don't see your bug report here, don't worry, as I still have a lot more work to do! Happy hunting! NEW - Strategic: When autotrader is in station and is looking to buy a resource from it, station stock ratio (how much it wants to keep as a stockpile) is considered, to ensure stations still have resources for production - Strategic: 1024 total randomized ship names - Strategic: New random name after buying ship - Tactical: Targeting overhaul. Threat assignment is now more efficient - Tactical: Kagayaki railgun model: added muzzle holes - Tactical: SFX for when camera stops facing/following ship - Tactical: Show weapon status (Idle, Loading, Engaging,…
- v0.2.2.1 - Resolution Bug Patch - 18 March 2026
- Tactical: The bug where the move line breaks when using a non-1080p resolution has been fixed in the tactical scene and tutorials 1 and 3. - Tutorials: The bug where the yellow line pointer under the Sara text box pointing to the wrong positions when using a non-1080p resolution has also been fixed. - Settings: Increased UI scale settings from "50% - 200%" to "50% - 300%" I want to be honest with you all. The launch has been a lot to handle on my own. I felt myself hitting burnout and recently took a break to destress, but this left me unable to see a major resolution bug, which I left unaddressed for too long. Back when Spacezero had two members, I focused entirely on the game development side while my partner handled the marketing and community aspects. But now that I'm doing things alone, I have had this massive blind spot. I was overwhelmed and didn't know how to handle the pressu…

There's still a lot of work to do and HEAT DEATH will be very different a year from now.

- v0.1.6d - POST-FEST PREP - 1 March 2026
v0.1.6 - POST-FEST PREPHey, everyone! Sorry for the lack of updates the past few days. I had some personal stuff to take care of, but it's okay now. My current priority is stabilizing the game and getting the full release version ready for release next week.

Thank you for being patient with me!PENDING- Tutorial 3: Rare bug where UI breaks during combat while player is selecting/deselecting ships and squadrons- Strategic: Hail station > Harbor > "Move ship to fleet" dialog box shows up with only one option (only one fleet in port).

- Status Update - 1 March 2026
Hey, guys. I'm very sorry for the lack of communication on my part. This is not my intention. The biggest thing right now is that I had some personal stuff to take care of during the past 4-5 days, with very bad timing considering that it's Next Fest week. The game was my very highest priority but it was overtaken by other things. It's okay now and I can focus on Heat Death again.Aside from that, since I'm just working on this game alone, I have to essentially min-max my time. Please know that I do read feedback when I can, I just don't have the time to reply to everyone yet.Right now, my priority with the game is ensuring that it is stable, so the most important feedback for me right now is the bug reports. And next week, I will be busy adding features for the full version before it releases. After the dust settles and the game is in a decent enough state, I want to finally talk to you…

Hello! I just wanna preface this by thanking all the playtesters for sending out some awesome bug reports so far! You guys found a lot of bugs that would have taken me a long time to find on my own. Just know that I can see all of your submissions and I appreciate every single one of them :)I also want to say that after you send reports, it may seem like it takes me a while to update the game. This is due to me living in a different timezone (GMT +8), so I could still be asleep hours after you submit reports. So please bear with me!I'll do my best to send out a new patch every day so you guys have more to things test.(Also, I just want to make sure, did a certain video play when you opened the Prometheus scene for the first time?)v0.0.9NEW- Bug report and suggestions subforums in the Steam community hub- Bug report panel: Buttons to bug report and suggestions steam subforums- Bug report…
