Игра жутко лагучая на среднем железе. Абсолютно конченная боёвка, неотзывчивое управление и камера, которую явно кодили отсталые дегенераты. Игра на разок - мехов пособирать, и то оставить в библиотеке гнить.
为什么这么大电流音啊,别的游戏都没这个问题
I'm having a lot of fun with MASS Builder. There are 25 campaign missions that you can get through pretty fast. They're a bit repetitive, but the environments vary which helps a lot. There are also 8 "Hunt missions" and 3 missions in their "Endless mode". However, the real appeal is from the customization. There are so many parts and you can customize almost everything on your mech and weapons. There's also 3 separate categories with upgrade trees for tons of different builds. I've heard ranged builds are weak, but I beat the game using exclusively ranged builds, so it's doable. Multiplayer is pretty much dead. I highly recommend if you like mecha games with tons of customization options!

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.

哪个男人能拒绝捏机子的魅力,更新有点慢,希望以后能更新出更多骨架结构比如四足啊什么的,或者可以自定义的真的可以喷射的喷口零件,以及让玩家自己捏姿势罢,你这默认姿势是真⑧行((
Poor sound design and dated game design bring down the actual gameplay of an otherwise pretty impressive mech customization experience. Not worth the asking price, wait for sale.
现在 EA的游戏 难得的 一直在更新的
จากประสบการณ์ที่เล่น ทั้งdemo ทั้งเกมจริง(พัฒนาอยู่) กินเวลาชีวิตฉันไป 100 ชั่วโมง+ กลไกการติดชิ้นต่างๆโคตรละเอียดเเละสนุกจัดรวมถึงอาวุธ ท่าทางการตี การยิง ได้ใจสุดๆ ทำให้ความเบียวหุ่นพุงถึงขีดสุด ทำตัวอะไรก็ขึ้นอยู่กับจินตนาการ เเต่ก็มีข้อเสียอยู่เหมือนกัน ด่านแรกกับกลางที่สู้กับมอนแม่งยากมากๆ ถึงพี่ปรับเป็นง่ายสุดก็ไม่ต่างกัน มอนเป็นล้าน ตีโคตรเเรก รวมถึงบอสที่แม่งไม่ได้เก่งเลย เก่งแต่ตอนมีลูกน้องช่วยยิงไม่หยุด 3-4 นัดก็ไปคุยกับรากมะม่วงยิ่งเป็นมอนหุ่นยนต์ที่มีอาวุธเหมือนเราหมดเลย เก่งชิบหายยิงเเรงยิงเร็วมีเยอะอีก ส่วนระบบอัพเกรดสกิลทีและอื่นๆก็ทำได้ดี แต่ก็อยากแนะนำอยู่ดี เล่นเถอะคับเพื่อชีวิตเบียวๆที่ขึ้น
Конструктор классный, но на параметры почти не влияет - единственное, нужно следить за весом косметических деталей, очень влияет на мобильность. Тюнинг и прокачка очень капризные вещи, долго нужно баланс подбирать. Мультиплеер никакой, ради него в основном и приобретался. Ждём обновы.
The customization in this is complex and daunting. Menus flow very weirdly. Lots of making a change, the menu exiting and then u re enter the menu to make another change. I could not get the build menu to function with a controller. I had to make custom colors for each weapon along with for the mech. Why in god's name cant I just use the colors I set up for my mech? Why do I need to redo it 7 times??? Overall very cool but a clunky time sink. I can tolerate the janky combat but some of the objective design seems untested. Mission 10's constant missile fire made activating the towers a test of precision timing. They objectives take too long to activate. This is not fun and is not engaging. The constant missile fire is also grating on the ears when there are 8 launchers firing at once. One play through of the level would have snuffed out this issue. PLEASE FOR THE LOVE OF GOD ADD A CONVERSATION SKIP. I waited a long time for this game to release and it's got awesome customization. The combat is terrible. If you just want to build mechs all day then this is a good game for you. If you want to pilot them for longer than 10 minutes, you should just go play something else. This game needs a lot of tweaks but I doubt they will be meaningfully fixed.
