The new ‘Government Actions’ and ‘Centralised building upgrades’ mechanics introduced in the Rise of the Republic campaign can be customised and applied to any faction (and the same holds for the new Etruscan victory condition requiring the faction to maintain constant ownership over a certain region).
Incidents defined in the database can now be easily triggered from Lua. Modders will be able to transfer regions between factions, spawn an army or navy in a chosen region, grant technologies through payloads, and restrict available technologies using scripted conditions. With Rise of the Republic out August 9th, modders will have access to more unit parts and more scripting options as well as the Mod Filter we brought into ROME II with Desert Kingdoms back in March.
