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 gam
0.13.0 Progress update2025-03-02Hello 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 Preview2024-12-14Welcome 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 Notes2024-11-28After 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
WIP: Update TImeline2024-11-10Welcome 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 s
WIP: 0.12.0 Mecha Asset Sharing System Preview2024-10-27Welcome 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 pai
WIP: 0.12.0 Assets Sharing Sneak Peek2024-10-12Welcome 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 playe

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 quest

WIP: 0.12.0 Sharing System update2024-08-17Welcome 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
