About Main Assembly

✦ AI summary

Main Assembly is a creative sandbox where you design and build robots of any shape imaginable, then program their movements with visual tools and test them in custom obstacle courses you create. Play solo through 100+ challenges or team up with up to three friends to construct worlds together and compete against each other's mechanical creations.

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.

What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Main Assembly has an excellent vehicle building system that players compare favorably to professional tools like Blender and other building games, but the game was abandoned by its developers shortly after release, leaving it in a bare-bones state with no ongoing support or content updates. While some players found it worthwhile for brief creative sessions, the lack of development and post-launch support makes it a risky purchase even at a significant discount.

Not recommended Sep 15, 2026
Interesting, but fairly bare-bones. Abandoned right after release. Might be worth a few hours on a heavy discount, but don't expect much more than that.

This is easily the best vehicle builder out there. I've played lego racers, lego 2k, trailmakers, terratech, etc. This one's so ♥♥♥♥♥♥ good, just from 30 minutes in the builder. It's legitimately like using blender.

Games like Borderlands 3: guns that roll, trees that branch

Games like Borderlands 3 have to do two things at once: roll a new gun every few minutes and make a skill tree worth planning. These manage both, and one asks you to craft instead.

Games like Dragon Age 2 are hard to find because almost no RPG keeps you in one city while it rots. These come close, from Neketaka to the streets of Serene.

Games like Noita, where the physics is the real enemy

Games like Noita for the two things it really does: spells you assemble yourself, and a simulated world that takes nobody's side. Seven picks, from a slugcat to a dwarf fortress.
