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.With a powerful and limitless building tool at your fingertips you can progress from a building beginner to an amazing architect. Every plate, chassis and frame is completely customisable! Tinker alone or enlist friends for your next big project. Build something amazing? Share it in the Steam Workshop!
Like everything in Main Assembly, if you can imagine it, you can create it- including multiplayer fun! Whether you want to chase, race or shove your genius creations in their face, the choice is yours! In sandbox areas you are free to play the game your way. Remember, friends who play together, stay together!
Test your inventions by taking on challenge packs! With increasing difficulty push your creations to the limit by testing their speed, survival, and handling through a series of challenges. Can’t do it? Don’t go nuts and bolts, alter your robot, build a new one or download a creation from the workshop!
In a game where anything is possible- don’t be basic. Every aspect of your robot is customisable from the size, shape to the colour. Think it’s lacking a finishing touch? Stick some googley eyes on it! The robotic-chic doesn’t end there. As you navigate through the world of Main Assembly you take on the role of a spherical marvel AKA a drone, complete with a tool kit of cosmetics!
Now you have a beautiful robot, bring it to life! By using the nodes in the powerful visual programming interface, you can set up controls for your robot. After getting the hang of it, you can dig deep into it and use Sensors to make logic for different types of automation. Or, equip rockets for explosive game play!
Your robots will take damage if they crash, fall, or take a hammer to the face! Advanced destruction systems enable bending chassis and damage that affects robot behavior. But don’t worry, you can iterate to improve and re-spawn your robot to crash it even harder!
