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…
TrainwizHello starchasers! You should have expected a new patch to coincide with the Steam Summer Sale; I'm a predictable kind of guy like that. There's not too much new stuff here: it's mostly fixing a ton of (some pretty serious) bugs in…
TrainwizHello Starchasers! Did you expect an update? A mainline update? I certainly didn't, not at first, but I met with the other members of our development team (pictured below) and we discussed the matter at length.We've reached the point now…
TrainwizHello, starchasers! It's our second year annivesary for Underspace's early access release, and we've been barreling towards the full 1.0 release at a breakneck pace, with only a few major tasks left before we enter our beta for that! The…
TrainwizHello starchasers! What, did you think you'd never see me again? Did the Doubt Gnome whisper his foul magics in your ears and make you believe like this wasn't something that was gonna be pulled off? Well, surprise! Multiplayer's here! Sort…
TrainwizHello starchasers! My two-week sabbatical is coming to a close, and there's been a few bugs unleashed by the last update (and the whole fundamental-change-to-our-entire-file-format) that required a fix or two. Since I was also able to…
TrainwizHello starchasers! It’s been a hot minute since the last patch announcement, hasn’t it. I’m sure the cats missed all of you, if they could understand such a concept.When was the last mainline patch? September, was it? Jeez, that’s a lot of…
TrainwizHello starchasers! No, this isn't the talky patch I've talked about, but there is news and a new opportunity for those willing to try it out. You want cat photos first? Alright, fine.Okay, got your fill? Onto more important matters! Beta…
TrainwizWelcome to September, starchasers! Now we all know it's about three days until that Bug Game releases, so all of us, myself included, probably don't give two rocks of an Ast's wing-thingies about any sort of other games at the moment, but…
TrainwizStarchasers! Hunters of the Union and beyond! Did you think I was done with you? Did you think you could let yourselves rest? We're done with patches when I SAY we're done (and when, you know, we've got multiplayer and stuff implemented).…
TrainwizHello again starchasers! Been a bit, hasn't it? Lot of bug reports piling up. Unfortunately for you and me, these past two weeks have been spent moving halfway across the country and then waiting for my actual work materials and computer to…
TrainwizWelcome one and all! Ladies, gentlemen, starchasers, sentient microbes and angry screaming swear crystals! The Steam Summer Sale has commenced and Gabe Newell has blessed our wallets with the blessing of being drained. My computer is packed…
TrainwizHello starchasers! It's been a hot minute or two since we last talked, huh? What was it, April? April seems like it was years ago. I bet you've been starving for cat pics, huh? It's taken quite a bit to get this update out, seeing as these…
TrainwizNew Update! Intergalactic Architecture! Check it out the details: Intergalactic Architecture Update
Camlann GamesHello starchasers! Today's April Fools so normally I'd be announcing something silly like selling ships for real money or adding battleships. But I don't make jokes, ever. So to that end, I'm releasing patch 1.42.0 for Underspace. This has…
TrainwizWelcome to March, starchasers! I hope you're having a better time of it than our cats did, seeing as they spent most of this month sneezing and being sick. {STEAM_CLAN_IMAGE}/35321791/b91e4fe0c407ae7b5bb1de930e862c5d1bba19cb.jpg They're…
TrainwizWelcome back starchasers! It's been a hot minute since I dropped a hot steaming patch onto your laps, how you holding up? Doing okay? Want to go back to sleep under the covers?…
TrainwizStarchasers! Anarchs! Those weird guys in Peerless that keep fighting over explosive cubes! Come one, come all, it's 2025 and our first patch of the year is now live. Is it the big update you've been anticipating? No. I posted that recap…
TrainwizWelcome Starchasers! Happy New Year, hopefully things work out for you, those New Year Resolutions get resolved, you work off that eggnog hangover, etc, etc. I’d waste your time with this preamble, but you and both know you’re here for the…
TrainwizHello starchasers! Did you have a good The Game Awards? Did you see that trailer without any gameplay? Yeah that sure was a trailer. Did your favorite game lose? My cat's favorite game lost and now he's overcome with despair.…
TrainwizWelcome starchasers! It's the Steam Autumn Sale (which takes place in the heart of winter for some reason) and predictably, we've got a patch just in time for you. I know you love patches, in the same way Mimosa loves her mechanical duck…
TrainwizWelcome back Starchasers! I recall saying that I was off to the Big Easy to gain ten pounds in gumbo and banana's foster, but it as it turns out when most of the good places are all within walking distance you actually end up losing weight.…
TrainwizHello starchasers! This is was originally going to be a cockpit hotfix for our lastweek gamepatch, but then I worked a bunch and now it's not. We're still not quite ready to showcase what's coming up for milestone 3, in the same way that my…
TrainwizWell hello starchasers! It's been a hot stellar minute, hasn't it? Did you think we were just going to leave you forever? We're not THAT kind of Early Access game, rest assured. But after breaking my soul and back to get Faces In The Fog…
TrainwizHello starchasers! I've returned from the Mothman, who was both very moth and very man, as well as received our cats from the Cat Stasis Facility, so everything is back to normal. Normal enough that I think you deserve a bit of a patch, eh?…
TrainwizHello starchasers! As promised we've got another patch for you this month, right before I take a small break to go off to the Mothman Festival (I made an oath to do so). This is mostly a big pass on all the new content, but I had some time…
TrainwizHello starchasers! We're nearing the end of the Space Exploration Fest, and I'm still out here on a beach sipping mocktails and reading sappy fanfiction as I take a well earned post-crunch vacation.…
TrainwizHello starchasers!, and welcome to Steam's Space Exploration fest. We'll be here all week, not only with a free demo to try (of course) but also a major new update with Faces in the Fog (our biggest yet) and a weeklong 25% discount. See you…
TrainwizWelcome starchasers! It's the first week of Steam's Space Exploration Fest, which we're proudly in, and with it comes our next milestone update: Faces in the Fog! This is a massive update that I've spent months prepping for and that adds a…
TrainwizHello starchasers! Right now I'm knee-deep in on next big update, but I've come back with a little patch for you. But I know why you're really here, you just want to see these furry bastards.…
TrainwizWelcome starchasers! I'm sick as hell (I mean I'm always pretty sick but I mean that I went to a punk rock concert and now I'm bedridden with the flu) but still managed to drag my mangled, disease-ravaged corpse body away from the warmth of…
TrainwizWelcome starchasers! I had mulled over delaying this patch a bit until we had something more, but a lot of the stuff here are fixes I think more than a few people would be impatient for. This also includes a big fix for THE VOID visual bug…
TrainwizIt's been a while starchasers! Have a sale, a big new patch, and some cats. Did you know that people got the game running on the 3DS and the Nintendo Switch? I have no idea how, but I was never that kind of engineer.…
TrainwizWelcome starchasers! Have a good week? Didn't die in the summer heat? Didn't get compared to a loaf of bread and get heinously angry over being compared to a loaf of bread like my cat?…
TrainwizHello starchasers! If you haven't seen it, we've announced our next big milestone update: Faces In The Fog. This is far larger than Gods & Corpses was, and has many new locations, quests, and features. We'll be sharing more detail on this…
TrainwizHello again, Starchasers. Good to see you. Because I DO see you. All of you. https://clan.akamai.steamstatic.com/images/35321791/b2c2d6708e88d819f6b1ee6929ae03908160b15e.jpg Sorry, I meant this picture.…

Camlann ProducerHello starchasers! It's Saturday and we're back on that sweet sweet patch train. Many of these bugs were found by you, our community starchasers, and many of these features or changes were also requested by them. We like to do that. Just…
TrainwizStarchasers! Welcome back. I'm taking my wife to a convention this Saturday and I'll be out all day, so, lucky duckies that you are, you get this week's patch early! It's a small one but there's some stuff there you'll like. I liked it. I…
TrainwizHey hey starchasers! How's your Saturday? Full of rain? That's thematically appropriate. We're returning to our weekly patch schedule now that Gods & Corpses is out of the way. It'll be a bit before our next big update (which is a true…
TrainwizWelcome starchasers! It's midnight and as a special treat we're rolling out our first major update: Gods & Corpses. {STEAM_CLAN_IMAGE}/35321791/992ae2b30351a90996bd89fecb066f586df392bb.png This is itself kind of a smaller prelude to some…
TrainwizHello starchasers! As you know last week we didn’t have a patch, mostly because I was in no position to be patching things, mostly because I was on the other side of the country, mostly because I was talking to people like Todd Howard.…
TrainwizHello starchasers! How are you- Cat pictures? Oh alright, fine. I keep waking up with 30 pounds worth of meowmeat on top of me so here you go. These Things. {STEAM_CLAN_IMAGE}/35321791/02391b1204cb984b52f22778c65ab195c47bac16.jpg Now I'll…

Camlann ProducerWelcome to next week starchasers! Another seven unfortunate days have passed through our shadowy midst, and another seven days of hardcore patching have came and went. Don't burn yourself out you say? Buddy I was at the farmer's market all…
TrainwizHello starchasers! Happy weed day or whatever. Is it weed day? It's weed day or something. That's important enough of a holiday to release a NEW patch, isn't it? It's been just over a week since Underspace has released now, and about a week…
TrainwizHail Starchasers. I trust by now you know the drill. https://clan.cloudflare.steamstatic.com/images/35321791/d9592d1d608c665268b37e4800cb360ce7eae1aa.jpg It's been almost one Earth calendar week since Underspace's release and we've already…
Camlann ProducerHello again starchasers! I hope you've been enjoying space. What's that? You fell in love with a microbe? Well don't do that. She views you more as a friend. She just won't love you the way Lady Mimosa here loves plastic bottles.…
TrainwizHello starchasers! We've still got a patch coming on Monday but I had some time today so I figured "Why not". Is it some special occasion? Some holiday? Homestuck day you say? Well Homestuck's terrible now so no. It's just a nice present…
