About
You’re the designer, engineer and architect if you can imagine it you can create it! Construct robots of any shape or size from eight-legged spider bots to eerie UFO contraptions. Engineer each and every appendage with powerful visual programming letting you dictate the bots every move. When you’ve completed your masterpiece, open the world builder and craft the ultimate obstacle course to push your bot to its limit.

Alone or with fellow inventors, envision your design then make it a reality.

Create a world in which your bots will be challenged. Craft tracks for racing or complex obstacle courses that tease out all those lovely design flaws you didn’t know you had.

Show off your designer skills first-hand with up to three friends. Build worlds together to challenge each other's bots in different obstacles courses and tracks. Or smash each other's creations into metallic pulp (more coming soon).

No friends? No problems. We’ve created a single-player mode with over 100 challenges to test your inventions.

Don’t panic, we don’t expect you to code in C# (we’re doing that). In fact, it’s entirely optional, but if you’re up to the challenge we’ve designed a powerful visual programming tool for you to enhance your creations.

Add (or take) from the thousands of already created bots and worlds hand-crafted by our dedicated fans from all over the globe.

If you want to test the limits of your construction, then drive it off a cliff.

if a game is published by team17, you can bet itll be forgotten and abandoned shortly after release. this game is no different. abandoned for years, was hoping for a sign of life, but nope. abandoned.
DO NOT BUY, GAME UNFINISHED AND ABANDONED. This all happened right after I bought it, I am really mad since this game had potential.
no updates for years...
Abandonware
Abadoned :\
Such potential but it's sad it died early.
Main Assembly gives creative players a robust set of tools to build and experiment with robots, provided they have the patience to learn its systems through trial and error due to a very limited tutorial.
great engineering game, more complex side though provides alot more freedom with what you can do. If your intrested in engineering, design, or anything related to this i highly suggest you consider getting this game. The controls/UI are a bit odd to use, but not hard to get used to. Some of the rigid 3D parts (like suspension and wheels) feel somewhat lacking in their ability to visually or physically change which can cause things like suspension to stick out of surfaces so they work or wheels to be too small when you change your design or other feature/factor. despite this, im sure there is some work around to this, though i have not found one my self. If you want something that is essentially a super simplified solidworks, id go with this. Though there is other games (such as stormworks) that can be alot more beginner friendly while providing similar freedoms to this game.
crashes semi often but game is pretty peak please add more settings cuz i want a lower camera sensitivity so i can use it to aim things
i bought this on sale for 1.99 but ive already made some cool stuff within three hours i can definetly see myself putting hundreds of hours into this game i highly recomend hurry up and buy it while its on sale
