About

Overview

Build and Crush is a physics-based Roblox game where you build structures from parts, destroy what others have made, and grow plants in crates to collect rare parts.

The three things you do in this game

Table
In short Building, destroying, and growing plants in crates are the three core activities, and all of them are available without spending anything.

Every session in Build and Crush revolves around the same loop. You place physics-based parts to construct something, you smash apart what other players have built, and you tend crates to grow plants that pay out rare parts when harvested.

02

How Garage Research expands your options

Tips
In short Every research level you gain opens up parts or building methods that were completely unavailable before.

Garage Research is the main way you unlock new content in Build and Crush. Each level you reach frees up parts that were not accessible before, and as you climb higher you also gain new ways to place the parts you already have.

Tips worth knowing
  • Each research level unlocks parts that cannot be obtained any other way
  • Higher levels also change how existing parts can be placed, not just which ones you can use
03

Building structures that survive

Warn
In short Because every part is subject to physics, a structure that looks solid can collapse the moment weight or force is applied wrong.

All parts in this game are physics-based, meaning weight, balance, and connection points actually matter. A tall build with a narrow base will topple easily. Heavy parts placed high up put stress on whatever is beneath them.

Worth watching out for
Placing heavy parts too high will collapse the structure when force hits it
Thin or short supports break quickly, so make your load-bearing pieces substantial
Weak connections between parts are the first thing to fail under impact
Building too tall makes the top vulnerable to attacks that a lower structure would survive
04

Growing crates for rare parts

Step
In short Starting a crate cycle early and checking back regularly is a way to collect rare parts that research alone cannot give you.

Crates let you grow plants over time and then harvest them for rare parts that are not available through Garage Research. The cycle takes a while from planting to harvest.

  1. Find an available crate look around the game for one you can use
  2. Choose and plant a seed pick the plant you want to grow
  3. Wait for it to grow the plant develops over time on its own
  4. Return and harvest collect the grown plant to receive your parts

Physics-based parts
Building pieces that are affected by weight and gravity, so how you arrange them determines whether your structure stands or falls.
Crate
A device that lets you grow a plant over time and then harvest it to receive rare parts.

Common questions

FAQ

Why does my structure keep falling apart on its own?

Every part in the game responds to physics, so an unbalanced layout will collapse under its own weight. Try widening your base, using thicker supports, and keeping heavy parts lower down rather than stacking them at the top.

Do crate plants always give rare parts when harvested?

Rare parts can come from harvesting crates, but they do not appear every single time. Running the grow-and-harvest cycle repeatedly is the way to collect them gradually.

Can I play this with friends?

Yes — the game supports multiple players at once and is designed around the fun of building and fighting alongside or against others.
