Closed beta is now live!
The Main Assembly closed beta is now live!
If you signed up for the beta, please check your email inbox for your Steam key!
Once you've redeemed your key, you will get access to the Main Assembly beta on Steam so you can start building whacky and wonderful things!

Want to know what's new? Check out our latest development blog HERE.
We're still busy crafting Main Assembly, so you may encounter a few known issues in this beta.
We added a bunch of new things and fixed quite a few bugs (RIP Spawn Lottery, you shall not be missed). However, there are some things from the previous beta that we just haven't had time to address yet:
Aerodynamics - we're going to take a swing at this before release, but the current version is pretty close to the previous beta. Sorry!
Drive Assist - drive motors still try to be helpful and occasionally get it wrong. Again, we'll look at this.
Build Mode - a lot of QoL fixes aren't live yet, such as updating the grid before you do anything, marquee selection, better mirror previewing...
Workshop - the new beta does not share Steam Workshop space with the previous beta. Any bots created and saved in the first beta will carry over into the full game at launch, but bots saved in this beta sadly will not carry over.
