Here is the page of custom maps, scenarios and such created by the Megacycle Entertainment crew.
Getting Started with Streaming Guide:
These scenarios (First Stand and Final Citadel) are two missions in a mini campaign that JohnMegacycle was working on way back. First Stand has your back against a wall with limited resources, constantly under attack. Final Citadel takes a different approach with tons of resources but a lot of land to cover and defend. Good luck, engineer!
