Remember the AMA announcement we had weeks ago? The answers to them are now ready for viewing! Please check them out down below! More answers in the comments section as well, as we exceeded word count in this news posts.Question: I hope to develop more diverse weapons, dual-wield ranged weapons, develop more mechas and accessories, and allow mecha parts to use more accessories.Answer: We hope to also provide more parts to you. We cannot allow for more than 8 accessories per part though.Question: When will we get a better color picker/tool? The current one is very primitive and unintuitive, while games like Armored Core and Gundam Breaker give us sliders for more accurate color choices than blindly spinning the wheelAnswer: This Color Selection Tool is a standard one across multiple image editing / drawing softwares. We like and are familiar with how it is. Why reinvent the wheel or copy…

Builder, we are still going to keep working on it. There are a few more features and systems that we'd like to add to the game, not just content updates, but let's not go too far, let's just stick with what's coming next.PvP ModeThis is a much requested feature to be added into the game, and honestly, we wanted to finish it before the 1.0.0 launch. However, due to various circumstances, we decided to not put this system out until further testing and multiplayer optimization. It will come in time as something to complete the multiplayer system alongside its nodes balancing. We cannot pro…
- M.A.S.S. Builder Full Release 1.0.0. LAUNCH! - 15 September 2025
Hello! We're finally ready to announce the M.A.S.S. Builder major update 1.0.0! We're finally out of Early Access into full release with this update, completing the whole M.A.S.S. Builder Campaign story! It has been a long journey up to this point, but it is not the goal, not at all. As we've always mentioned, M.A.S.S. Builder is a dream project for us and we're continuing its development far into the future. However, we won't talk about them today, as today's main topic is about the update! There will be a "What's Next" post next week detailing what and how we're continuing to work on the game after this full release. For now, let's head to the patch notes. Additions:Weapons Attachment SystemThe weapons attachment system is a system that we've wanted to add since the earliest days of M.A.S.S. Builder. It is the fantasy of bringing your own weapon into battle and seeing your M.A.S.S. un…

As promised last week, we will be giving a whole set of explanations on what it covers, how it works, and the changes that we'll be making with the Bullet Launchers attachment system that we'll integrate into the weapons attachment system. Without further ado, here is the weapons attachment system.You can now attach your Close Combat weapons, Shields, Bullet Shooters, Energy Shooters, and Bullet Launchers onto certain parts of the M.A.S.S. unit. The only weapon that won't be able to attach to your units are Energy Launchers, as they behave differently from the rest.In regard to Close Combat weapons, Shields, Bullet Shooters, and Energy Shooters, you will be able to choose a style of attachment. "Hide" means that it won't be attached anywhere just like what the game always had been. Dual means the weapon will be attached on…

This mission will feature an area filled with the highest concentration of Void particles, where Quarks will swarm out from every where without fail. Fortunately, you won't be working alone in this mission.

- Incoming Patch Status Update - 3 August 2025
tl;dr Update will be coming in SeptemberHello everyone. First off, let us apologize for not having frequent updates like before and making the project feels like it's dead. We've been busy working on the various systems to make the next update as best as it can be. With that said, we're finally ready to announce the upcoming update for M.A.S.S. Builder, which will be full release version 1.0.0.Wait, aren't we going with version 0.13.0? In contrary to the last announcements, we're going to go ahead with version 1.0.0. instead. At first, we wanted to quickly finish the final missions of the game in 0.13.0 and then make a final polish of the game, adding more systems and contents before releasing it out of early access However, we later realized around March that fine-tuning the bosses and missions for the update will require extremely meticulous amount of work to make it our best work, an…
- 0.13.0 Progress update - 2 March 2025
Hello everyone! Sorry for not having any new WIP update for these past months. We are still currently working on giving 0.13.0 its deserved quality thus we don't have any news regarding its release date or time yet. We wanted to post this as a way to say we're still working on it and not to worry, we'll deliver the next update as soon as it's finished whenever that is. 0.13.0 is where we'll complete the story missions of M.A.S.S. Builder before we go back to review the whole game at a later date, so we wanted it to be as best as possible within our capabilities. For now, here's a Quark rolling out!
- WIP: 0.13.0 New Boss Preview - 14 December 2024
Welcome back to another WIP update for 0.13.0! As we've updated the game with our sharing system a few weeks ago, we've now resumed our work to the story content part as we've promised before! Today's WIP update will be a short one though, as we wanted to show you a really early model of an upcoming boss. While it doesn't look menacing over here, it's actually one of the bigger Quarks that you'll have to face in the latest missions of the game. Hope you liked how it looks, we'll continue updating you all on our progress in the coming weeks. That'll be all for M.A.S.S. Builder today. Hope you all have a great time!

- Upcoming Updates and Patch Notes - 28 November 2024
After months of working on the M.A.S.S. we're finally ready to announce the update release timing, which honestly isn't far at all. In fact, we'll be releasing the update on this coming Saturday November 30th (GMT +7). As we've mentioned in an old news post, we wanted to release this update just to provide a way for players to share their builds as soon as we finished it thus the update will only feature the sharing system, aptly named as the M.A.S.S. and nothing else. There will be no new missions, no new contents, or any balance updates at all. As such, this patch notes will be a recap on how the system works! Patch Notes: Added the M.A.S.S. (Mecha Asset Sharing System) The Mecha Asset Sharing System is a system where players can easily share their M.A.S.S. units with each other through an export and import function. To paraphrase an old news post, players will be able to export and i…
- WIP: Update TImeline - 10 November 2024
Welcome back to another WIP update for 0.12.0. This week, we're talking about the timeline of 0.12.0. Let us just get it straight out, 0.12.0 featuring the M.A.S.S. will be released at the end of November. Patch notes incoming soon. What about the big guy on the banner? Well, that's something to look forward to in 0.13.0. Let us delve further into this. We have decided to break all the updates we wanted to make in 0.12.0 into a few pieces, one of them is the M.A.S.S. and the other is the ending of M.A.S.S. Builder's story. We thought to ourselves, since the M.A.S.S. is mostly finished, why don't we just update it for our players to have fun sharing their builds ASAP? We know it's one of the most requested systems and we don't want you to have to wait until everything else take months to finish. Also, Christmas is coming up and we think sharing builds should be a nice Christmas gift to o…
- WIP: 0.12.0 Mecha Asset Sharing System Preview - 27 October 2024
Welcome back to another WIP update for 0.12.0. We're going all out in showing you the M.A.S.S. or the Mecha Asset Sharing System this week! Hopefully, it will be able to provide you with the satisfaction as it did to us when we were discussing and creating the system. Let's get into it straight away. First, we're adding a new customization mode "Preset" to handle the exporting and importing of assets into the game. You'll find it in the usual place alongside other options. As we've shown in the sneak peeks before, you can choose to export either as an individual slot or a set. In addition to that though, you can also choose to export your paint or decal data as well. When not exporting paint data, the parts will be set to gray color to mimic priming a model to get painted later. After all selections, the thumbnail on the left will also get exported alongside the Asset file. You can move…
- WIP: 0.12.0 Assets Sharing Sneak Peek - 12 October 2024
Welcome back to another WIP post for M.A.S.S. Builder, featuring the Assets Sharing System (M.A.S.S.) once again! It's just a small sneak peek to how we've designed the systems and what it could eventually do! For now, it's just about the "export" part of the system, where you can export either a preset "group" or "invididual" pieces of a slot. The example above shows the "Body group" which includes the Upper Body, Middle body, and Lower Body slots. There are multiple groups available like Head, Legs, Arms, and many more that would allow the ease of usage. When exporting, a thumbnail will also be created alongside the group or piece and players can customize their thumbnails during the process to an extent such as the zoom amount of the piece, the angles, and even to show the frames attached to the piece or not. These are all to help players show the parts that have been exported and it…
- M.A.S.S. Builder: Impressions from Tokyo Game Show 2024 - 5 October 2024
Welcome back to another WIP for M.A.S.S. Builder! This week we'll talk about the Tokyo Game Show 2024 event that we've attended last week! First of all, thank you to everyone who visited our booth during the event! It's great to see the faces of people still following the development of the game and hearing about the love you still have for it. This is our first Tokyo Game Show ever and it was as overwhelming as we thought with all the great games at the show. But, M.A.S.S. Builder has garnered a lot of interests from you guys, and we've had a great time showing the game to everyone as well as welcoming you fans who came to ask a lot of questions about the progress of the game. The free stickers were a hit to most people who wanted something from the game. We've also got a shikishi from our artist available for anyone who tried the demo at the event. Now, let's head back to providing WI…
- M.A.S.S. Builder is heading to Tokyo Game Show 2024 and WIP update! - 16 September 2024
There are two things we'll talk about today! The first is what was listed in the headlines, M.A.S.S. Builder will be heading to Tokyo Game Show on September 26 - 29 at the indie games area! Our booth will be represented by Sekai Project, our publisher, and we'll have both English and Japanese speaking personnel to welcome you! There'll be a demo station for those who have not tried our game yet as well as developers who will be ready to answer any of your questions and concerns so feel free to visit our booth to do so! Now, aside from the news, we'd like to update you on the current WIP of the game as there haven't been one in a good while. This is due to the things we're working on, notably the builds sharing system (named the M.A.S.S.). Systems are extremely difficult to show in WIP as it's mostly a back-end coding work but we'd like to say it's still an ongoing system we're working o…
- WIP: 0.12.0 Sharing System update - 17 August 2024
Welcome back to a new WIP update for M.A.S.S. Builder, this week featuring our still-in-design M.A.S.S. feature! As the phrasing suggested, we are still designing the feature but have explored a lot of options on how it will work which we shall share with you today. First and foremost when thinking of this new feature, we looked back to how we can implement it into the game without breaking the game itself. To that, out of all the multiple choices that we have, upgrading an existing feature to implement a new one is what we've decided as the best and easiest. So, which feature is the easiest to work with? To us, it's importing M.A.S.S. units from one slot onto another. Upgrading the feature to be able to export the unit in some method, then importing it into a slot just like you do with other-slots-importing should be the best method out there. It will also help with the problem of misc…
