-- Layered-modding demo: this runs AFTER data/maps.lua, so it can reach into a
-- map the base game defined and change it. Here we bolt an extra armour skin
-- onto the Proving Ground enemy fort, making it a tougher target.
--
-- A mod could equally `table.insert(Maps, { ... })` to ship a whole new map;
-- see data/maps.lua for the shape of an entry.

local m = FindMap("Proving Ground")
if m then
    table.insert(m.structures, {
        name = "enemy outer plating",
        beams = {
            -- a second armoured skin one unit in front of the fort's face,
            -- tied back to it so the whole thing stays triangulated
