Do you mean like you can't use certain structure, until something happens? If that's what you mean, I don't know how to do it... Unless, you could somehow give the player a tech with the script, then you could have that structure require that tech. I don't really know 

Thanks! That makes a lot of sense! I'll be sure to check other scenarios and binaries then.  In addition, I was asking about making changes like structure availability. Is that also something I can edit via Atlas or is that a script thing?  Thanks for the link! I'll be sure to check it out.

Maybe, but it is not my case. I have seen recently CNC machines running on Windows NT, large printers running on Windows 98 and Windows XP, a SCADA running on Centos 5 etc.

I keep forgetting to do this....   https://gitea.wildfiregames.com/0ad/0ad/pulls/9124
