Main Assembly -- Steam -- Instant Delivery

In Main Assembly take on the role of a drone with the ability to design and build robots for your everyday needs! Create unique ways to overcome various challenges in single-player or jump into the Sandbox where you can craft and play alone or with other players. Challenge yourself and your friends to create the most exciting looking robot using a freeform crafting tool and modular parts, and then control them through powerful visual programming. You can also customize your robots by changing the colour palette and drone cosmetic accessories for that personal touch.

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.
