M.A.S.S. Builder is a promising gem for mech enthusiasts and fans of deep customization. While still in early access, the game already shows impressive potential as a sandbox playground for creating personalized mechanical warriors. The sheer depth of customization is remarkable — from armor designs to weapon loadouts, every detail feels like an invitation to experiment and perfect your own combat machine. Pros: ✅ Extensive Customization: The highlight of M.A.S.S. Builder is undoubtedly its robust customization system. Whether you're aiming for sleek, agile designs or bulky, tank-like powerhouses, the options are vast and rewarding. The visual freedom ensures that no two mechs feel the same. ✅ Satisfying Combat Mechanics: Combat feels fast-paced and responsive, with plenty of room to develop unique playstyles through your build choices. Experimenting with different weapon types — from missile barrages to beam swords — offers a strong sense of variety. ✅ Sandbox Potential: The game thrives as a creative platform. Players who enjoy tinkering with designs and pushing mechanics to their limits will find endless hours of enjoyment. Areas for Improvement: 🔧 Sound Design and Audio Quality: While combat feels solid, the sound effects often lack the punch and impact needed to elevate the action. Explosions, weapon impacts, and environmental audio could use refinement to match the intensity of the visuals. 🔧 Story and World-Building: The narrative feels underdeveloped, leaving much to be desired in terms of immersion. Expanding the lore, improving dialogue, and adding memorable characters would greatly enhance the single-player experience. 🔧 Multiplayer and Co-op Features: While there’s incredible potential for online collaboration and competitive modes, the current multiplayer elements feel limited. Expanding these features could turn M.A.S.S. Builder into a true social experience where players can showcase their creations and engage in thrilling battles. 🔧 UI and Menus: While functional, the user interface could benefit from improved clarity and streamlined navigation, especially when managing complex customization options. Final Thoughts: M.A.S.S. Builder is shaping up to be an impressive sandbox experience with exciting gameplay and limitless creative potential. While the game still has room for improvement — particularly in sound design, storytelling, and multiplayer — its foundation is solid. With continued development, it has the potential to stand out as a must-play title for mech lovers. For those who enjoy building, experimenting, and refining their designs, M.A.S.S. Builder already offers plenty of value. It’s a game worth supporting, especially if you’re excited to be part of its growth.

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,420 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.

как редактор мехи - ок как игра с геймлеем - абсолютно нет супер сырая индюшатина максимально всратое управление ужасный отклик мехи кастомайз не влияет на статы и перки, так что смысла в геймплейном плане в нем нет покупать сейчас? только если за 200 рябчиков
If you like customization and medium level smashy mecha combat, this game is so far up your alley. Its a lot of fun to customize and specialize your loadouts, bordering on madness due to the shear amount of combinations you can make. Highly recommended.
This Game is different than other Mech Games. Simply put this game has over 500 plus parts to customize your Mech the paint set is wonderful and easy to use. The story could use some work and for this game to have come out somewhat in this era I feel the story should have been narrated with actual voice actors or at the least AI. Either way in 2025 reading the amount of dialogue this game has is a little rough. The game plays like a dynasty warriors variant which is fun and all the enemies on the battlefield equals more fun. Now i ask when can we expect more dev support in the way of graphical updates and or voice support?
Honestly I have fell in love with fully customising a mecha down to its weapons. If you are a huge giant robot fan jump in.
As things stand today, I can only recommend this game for what is clearly the focus thereof, that being the customisation. Making and refining your MASS is satisfyingly in-depth. But what you need to do to get all the blueprints for the armour and weapon parts, the combat, is a chore at best and torturous at worst. I really hope they take the time to improve the combat, but the feel of hits and damage is mostly absent, and the ammo constraints make melee the only viable answer in most cases, which sucks, because taking damage is much more frequent in those cases, and even that isn't communicated well. And suddenly you're dead, but that is also of very little to no consquence, as you can just revive yourself at effectively no cost. In short combat feels terrible, but you need to get good at it, if you want to get all the cosmetics remotely efficiently.
BIG robot cool and customizeable
커스터마이징이 약간 어려우나 갓겜
