[How to give a player an upgrade in a trigger script?]

I am working on a modified version of Survival of the Fittest in which I want the attacker to gain upgrades as time passes.  Is this possible?

Thanks

They are in maps/random. They are scripts not actual maps.

What are the higher level folders? I'm on linux and installed 0ad with snap, but none of the folders in ~/snap/0ad contain the maps that the game came with. Only the ones I made in atlas.

I've been trying to edit the random map "Survival of the Fittest" but I can't find where the files for it are. alternatively is there a way to download the map files and put them in the same folder as the atlas files?
