OpenRA

Ages ago there was a cool map where there was 1 defender with loads of prebuilt & assigned structures & units vs attackers (who started with nothing).

I dont have that map anymore but would like to make one. My question is how to. How do I give one player buildings and units??

If anyone has a map like that, I can use as a guide or any other useful information (or links) It would be appreciated.

In the map editor you can place buildings assigned to a player by using the tab above the actors tab which displays "Neutral" by default. You will need to place their spawn first though
