About this game
Afficher plus Afficher moins
“A future in where humans lived a prosperous century and technology advancing beyond space and time,” that was what humanity should have been if not for the sudden appearance of unknown beasts of the void. A large portion of humanity were gone in the moment. War for the survival of humanity broke off all over the world, changing landscapes and settlements into warzones. Humanity were forced to relocate into shelters and reinvent their technologies into weapons of war, the M.A.S.S. technology.
M.A.S.S. Builder is an Action RPG with players piloting a M.A.S.S. (Mechanical Assault Skeleton Suit) as a commander of a private military company, setting out to help combat the threat of Quarks. You will build, customize, and fight to save the world, or at least, have fun creating and customizing your perfect mechanical suits.
The game features an in-depth customization system that has a clear distinction between equipment that gives status and equipment of pure aesthetics. You will be able to customize everything to suit your playstyle while looking good in this fast-paced mechanical combat.
Key Features
Customize your own M.A.S.S. without the worry of using cool looking armors with low stats, all parts don't have stats!
Fast paced movement through the battlefield with boosters for you to move around and attack through your enemies.
Fight against hordes of beastly aliens called Quarks, and giant ones that will aggressively hunt you down.
Pick how your weapon looks and shoots with hundreds of parts available to mix and match.
A world compelling and rich with information for you to immerse yourself in.

The game is just very good for building flexibility but the gameplay is very boring and repetitive. Besides enemies are always the same and backgrounds/scenarios are mainly the same.

the detailed customization is what I was after, and that *is* cool for what it’s worth. But the gameplay is mid and the story… what story 😭 I can’t get past ts it’s like I’ve experienced the great misfortune of stumbling upon some horny fifth-grader’s online roleplay as soon as they discover anime tropes. (And can’t even just ignore it and play for the customization because I would have to play through to unlock everything)

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.
