Bon jeux de roboto seul ou en coop
M.A.S.S Builder es un juego de construccion de mechas y es un juego muy de nicho, muy.. cafe para cafeteros. La libertad que tienes a la hora de crear tu mecha y personalizar tanto la estetica de la armadura como la estetica de las armas es muy muy buena. No solo por la cantidad grande de partes, sino que ademas el juego te permite añadir formas nuevas y personalizar hasta en que posicion quedan las distintas armas. ¿Ahora, y el resto? Los graficos, sin mas. La historia tipo anime shonen, meh, el gameplay muy torpe y muy meh, la meta progresión y las "builds" directamente mala, el combate tiene 0 profundidad, las misiones son todas de tipo arena (llegas a un mapa pequeño, matas oleadas de bichos y a correr), el combate tiene 0 profundidad... El juego puede llegar a ser divertido a ratos, sobre todo si eres muy fan de los mechas y los juegos asiaticos de este tipo, pero si tuviera que darle una nota, le daria un 5, quizas un 6 por la personalización. En cuanto a contenido.. en las 7 horas que llevo me da la sensación de que no he llegado ni a la mitad (quizas un tercio), aparte de eso, el juego ofrece lo que ofrece desde el principio, es decir, lo mismo que haces en la primera hora de juego lo vas a hacer en la septima y en la hora numero 50. Conclusion: ¿Recomendaria este juego? Pues para el publico general NO, solo lo recomendaria si eres muy muy fan del anime, de los juegos asiaticos y de los mechas (si, las tres cosas juntas) ya que la fantasia de crear el mecha de tus sueños (tanto en armadura como armas) creo que la cumple muy bien, pero en el resto de apartados flojea demasiado.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

Its an awesome game. I'm a sucker for customization and this game has tons of it! Not only can you completely customize your mechs you can also make your own customized weapons. Great game for GUNPLA fans. You have to complete missions to unlock blueprints for more armor and weapon pieces. But the arena style battles are very quick and enjoyable.
affter customizing\painting the mech you can go into fun battles i love the look of these options even from the start love the color options
Yeah, it's pretty awesome, if you're into this kinda thing 10/10
เกมดี
