unos de los mejore juegos de mecha para contruir lo que quieras como quieras solo le falta poner un modo para poder transformar el mecha que construyas como el gundam z en forma de avion
根本没有中文啊
I wanted to give this game a very positive review, however, I now have an error that causes my game to crash when I load in to campaign mission 11. I feel like I got duped by the developer, and based on other comments it seems I am not the only one. I am going to investigate getting a refund. It's really too bad. Buyer beware, this game is super fun. if it works.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,419 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Overall great game, AMAZING customization allowing for incredible detail to be added to your mech as you progress. The gameplay is fast paced and challenging, which leans well into its various aspects of tuning your mech and arsenal to handle different situations. The difficulty spikes a few main missions against a giant fish monster, but it's more manageable if you actually go back and grind a few missions to unlock new parts and farm the materials to unlock new tuning options that make the difficulty far more manageable. It simulates the ever growing threat of the enemies as the story progresses, making new advancements in M.A.S.S technology add to the immersion. The few issues I have are that there isn't an auto lock on function for melee combat, so you have to swing a bit more wildly if you don't bind the lockon key to your side mouse buttons, but that's manageable. My only major gripe is that ranged weapons fall off QUICKLY. They are always useful to deal with shields on some enemies, or to continue to deal damage while disengaging to allow your shield to charge, but melee weapons deal drastically more damage than your heaviest hitting options for ranged weapons. All i all though, well worth the current price tag, and with it still being unfinished they're bound to adjust some things, rework others, and add more each update.
Lots of fun. A great blend of Gundam and Pacific Rim. My only real criticism is that the painting needs another pass. It can be very specific, and that's great, however doing a quick paint job can be way to time consuming.
MECH REVIEW: 5/5 Top notch mech customization, from armors, to x,y,z scale, rotation or position, to custom primitive shapes that you can add, allowing you to build Gundams or well known mechs from other anime. GRAPHICS: 5/5 Graphics wise, I love the rendering of the mechs, they don't look too cartoony, and mechs looks great from a variety of decals, and custom paints. STORY/DIALOGUE REVIEW: 2/5 Story wise, the dialogue can be a drag as there's little voiced dialogue and story happens like a visual novel with a looped avatar as they deliver their lines, it can be quite verbose and honestly there's probably a decent story and lore but I mostly skipped through most dialogue as there's no dialogue choices that can affect the story- I find the way the story is delivered a bit bland and and probably needs more polish. EDIT: After playing a bit more of the campaign I bumped up my evaluation for the level design from 2->3.5, later maps are actually bigger, but there are still places where moving around bumps you into invisible walls- but it's not as bad as I thought. Also, areas with ocean/water can sometimes get annoying- they probably designed it that way but I don't really enjoy the parkour around my maps and instant restart after falling into water. LEVEL DESIGN: 2->3.5/5 There's verticality (Jump and flight mechanics) but the map itself is pretty confined (Not really expecting an open world) but the map design can feel a little constrained in some areas. This might seem offensive to the developers but the level design doesn't really show case your mechs mobility as you find your mech bumping into invisible walls a lot of times. This is a difficult issue as they can't just add random elements like walls or big rocks to serve as walls as it would hinder player view, but the barren land around the map doesn't really help sell immersion when there's invisible walls everywhere. GAMEPLAY: 4/5 As for gameplay itself, the various configs for weapon are pretty fun to try, there's development upgrades that can be unlocked that requires materials dropped from missions and various playstyles that can be configured or fine tuned to your playstyle (Close combat focus, Speed, Shooting, CC, Elements, etc...). QoL Complaints: >There's a variety of weapons and can be customized, but it can be difficult to tell what a weapon customization does as there's no preview for it(Like what does Auto ->->-> mean or photon means, etc...). Best way to find out what a weapon customization does is to equip it and try it on demo mode which can be a drag when trying various weapon configs. >Armor, painting and decals where a little funky in the beginning, the hyper customizability of the armors and look of your mech kinda sacrificed some UX design principles, making it a bit hard to figure out how to color each part of your mech. I would suggest locking some options in the beginning and then slowly unlocking each customization option with a tutorial. This would help with information overload as there's too many things to look at in the beginning and new users can feel overwhelmed and might feel put off by the learning curve to fully customize their mech. EX: Only some basic parts are unlocked in the beginning, like the head, and then "storywise" it gets damaged so you have to replace the head through a tutorial. It fits both the lore and will teach the player how to configure their Mechs armor slowly without making them feel overwhelmed with all the options and parts already unlocked. In my experience, it took me several times to pick up this game because it felt like the learning curve is like blender just to customize your mech- which is bad game design in my opinion if I were to put it bluntly. By locking some of the parts(optional), and slowly teaching the player how to change part, color, decals, and even custom shapes, it eases the player into the "MECH BUILDING" which is honestly the BEST and PERFECTed part of this game. QoL TLDR: Dialogues, tutorial are too verbose, Weapons configs changes are not obvious, needs a better tutorial to ease the player into the MECH building workflow. OVERALL: 4/5 Despite the low story rating, some issues with Quality of life improvements, not the best level design, this game gets a solid recommendation simply because it's primarily focused on the MECH BUILDING which is extremely the BEST and well developed part of this game AND gameplay is fun enough to see your MECH BUILD destroy enemies with custom weapons, swords, axes, scytes, rifles, blasters, missiles, lasers, and more... it would be nice for the game lore and story to develop into something more, but for now it's a Gunpla fan's dream MECH custom game.
테무산 아머드코어 훌륭한 커스터마이징에 폰겜같은 액션성
Really disappointing. Don't get me wrong, MASS Builder's customization is completely unprecedented. That is the biggest thing that sets this game apart from the others of it's type and the main reason why I wanted it. On the technical scale, the game's pretty polished. BUT... I mention the building being good - this is only after you can navigate through the absolute nightmare that is this game's UI. I've played games with very unintuitive user interfaces before, but I think this one takes the cake. The combat is... fine, I guess, aside from a few enemies being a little too bullet-spongy. However, major problems surface when you realize how exceptionally cheap feeling that combat is - there's no feeling of impact at all. Whether you're shooting at enemies or hitting them with your melee. Melee ESPECIALLY. Then there's the issue of the game's story. It would be fine - if it wasn't being presented to us in continual dialogue boxes. It gets to the point where it drags out for way too long and makes me question the genre of what I'm playing. I didn't come to play a visual novel, I came to build a sick looking mech and beat up the enemies. It absolutely nails the building aspect, but everything else is either just "eh it's ok" or frustratingly bad. Even for the sale it's not worth it. 3/10.
游戏很好,更新很勤快。但是没有中文
Customization is incredibly in-depth, you can customize quite literally EVERYTHING Gameplay is alright to me, everything is just bullet spongey, but if you get dodging and combos down you can pretty much just wipe everything pretty easily I'm addicted, and I got the game 2 days before this review was made and already sunk 24 hours into it.
