Reviews
I really enjoyed this game since I've been a fan of games like Gundam Breaker and Armored Core, so if anyone else is into games such as those, along with having some arcede like charm and RPG elements mixed in, you'll have a grand ol' time. The customization is top of the line and the possibilities are practically endless when tinkering with your M.A.S.S.
The story is that monsters have largely destroyed the world and mercenary companies equipped with mechs head out into the wilds to protect the last bastions of society from these beasts. But not all is as it seems as an unknown force is plotting against humanity in it's most desperate hour. It's a simple story, and you've likely seen something similar, but it's serviceable. It's pretty obvious, unfortunately, that the dialogue was written by someone unfamiliar with the English language. You'll still likely understand what's being said, but wonky grammar and "Wall-o-Text" will likely be a bit grating. The core gameplay is rather simple. I don't want to delve too deeply into combat; just know that while it's simple, it's influenced a lot by how you customize your mech. What melee style you use is determined by what Weapon Head and Grip you use. Your missile pods behave differently depending on what particular pod you equipped. Guns as well act differently based on your barrel, grip, stock, etc. You can have a ton of fun experimenting with different setups, or just stick with your favorites. The choice is yours. But speaking of choice, I'll briefly mention the customization. You have TONS of options after playing for a short while, and things are constantly being unlocked for you along the way. It's all cosmetic, at least as far as the mech itself is concerned. If you really put your mind to it, you could make almost any mech you wanted, but it will take work. The customization in this game is the selling point. The combat isn't bad and gives you a meaningful way to engage with your creations. It's overall a fun time, and any mecha fan should at least try it.

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.

什么都好,就是这汉化太痛苦了。
Fun game, great customization
躓いたとして 他の人の作品を参考にしてみたい!という人はディスコードの方にあるので そこにプリセットファイルをアップロードしてくれている人がいるのでそれをフォルダに入れることで再現できます なるほど、こうやって作ってるのかーなど勉強しながら自分の機体を作っていくといいかもしれないです
Ngl, underrated and incredibly addictive.
2021年にプレイして、「発売直後のアーリーならこんなもんかな?」とプレイ中断し、 そろそろ充実したかと思って再開してみたものの、依然変わらず。 武器や機体をいじれるのはいい。戦闘ののっぺり感とボスのイライラが改善されていれば嬉しかった。
This game has a level of customization that lets Mecha-fans like myself very happy. You can essentially bring any angle of creativity into the fight! I can't wait to see where this game goes!
I really wish Steam had a Mixed option. Bought this back in 2022 while it was Early Access, didn't much like the gameplay at all so I played it on and off every now and then to see what had changed over the years but it turns out the gameplay is mostly the same as it was back then with some good changes but not really enough to draw me in completely. I suppose if you don't care much about the gameplay and you're just here for the mech builder then you'll have a great time cause that aspect of the game is fantastic and you can do some really cool stuff, there's a large variety of parts and attachments to play around with and you can even build your own guns which is awesome. I don't think it's a bad game just that it's not for me, but after the amount of time I've played I just don't think I enjoyed my time with it as much as I had hoped I would. Pick it up if you want a really cool mech builder with some decent gameplay on the side, but if you're looking for something a little more complex I'd suggest looking elsewhere, or waiting for a sale.
