Hello starchasers! Been a hot minute, hasn't it? I was aiming to push this patch to the main branch earlier in the year, around the end of June, but there was SO much testing, fixing, and work that had to go into it on top of everything else in my life that it ended up getting pushed by pretty far. Perks of working on this by myself, I suppose. You're just here for cats though, I know.

I debated delaying this update until a proper 1.0 launch, but so much of this represents such a fundamental change for Underspace under the hood that I felt that getting it into the hands of you, the players, soon rather than later would only be a net benefit to society as a whole, so here we are.

Update Overview

Modding! The name of the game here is modding. Underspace previously had mod support for a variety of things like ships and equipment, but with this new update I've brought forth a lot of new modding features. So what can you mod in Underspace now?

Uh.

Well.

Pretty much everything! This includes writing new code, quests, random missions, support for modding star systems, stations, regions, universes, storms, etc, etc, etc. Damn nearly everything is now data driven to an extreme amount, but that's not all.

Let's say there was a game out there, another game, that was beloved and very similar to Underspace but handled all of its data through easily readable nonliable text files. What if Underspace's SDK now contained an importer that would read that data and recreate the data in that file to be accurate to Underspace's format?

Just saying, that's a thing now. Modders have to do some legwork if they want it working in full, but it'll do a vast amount of the basics for you. Just, you know, if you want to. And from what I've seen, people want to and are.

With the massive amount of content now available to be modded for players, we've switched away from one single modding pdf (which was a monster to maintain) to a much more viable modding wiki! I'm still in the process of writing the massive amounts of documentation for this (because again, I am a single person working on a 300 hour game and trying to document the hundreds of scripts and behaviors in this game is a nightmare even for an actual team, especially since all that source code can be accessed and new scripts can be written by the player), but so much is already there!

On top of that, multiplayer also has a ton of new things. Quests, world states, bosses, and all of that is now properly synchronized. Bosses have also gained new behavioral aspects to let them deal with multiple players, such as big snake monsters not just prioritizing the player.

With this in mind, multiplayer now sits in a near feature and content complete state. Some additional bits (such as a dedicated server mode, more admin commands, the multiplayer campaign, and of course tons of bug testing) still remain, but my original fever-vision of a game where you and your friends strike out into the starry unknown and get killed by a ghost starship are finally a reality!

Let's get into the actual changelog now.

Changelog is as follows:

1.0 Development Update

We're barreling towards 1.0 now with this latest release; my task list being little more than "voice acting and the multiplayer campaign". Many voice actors, namely the ones I could more easily get ahold of, have recorded their bits and bobs over the past few weeks, and the multiplayer campaign is getting plenty of its content finalized and detailed. No spoilers, but have some screenshots of the new places you'll be visiting once 1.0 launches.

There's still no concrete release date for Underspace's 1.0 launch, sadly. Since a huge amount of that is contingent on sweeping through the gargantuan amount of content in game and making sure it works, it's hard to estimate a time for that, particularly with such a small team. I'll have more for you in the coming months, but barring bugfixes this patch (1.55.6) will most likely be the last major patch before 1.0's release.

Until next time, starchasers!
