The main goal of this mod is to create a new faction ability and to improve the cities defense system for the AI players.
Engineering Faction ability (cost 1) : unlocks 3 unit design abilities, at Labor cost.
- Builders will allow the unit to build an outpost. Unit disappear once the outpost is built
- Settlers will allow the unit to settle a new village. Unit disappear once the village is built. The ability is unlocked with Civics Tech
- Road builders will allow the unit to .... well, build roads. The ability is unlocked with Trading Tech.
Note that the basic Pioneers (at Gold cost) are not modified but still useful.
Fortifications can be built in all the Engineers cities, and they're always upgraded (more troops + unit bonuses). As usual, only the Fortress city type can build Fort / Castle improvements, which are also upgraded (more troops + unit bonuses).
Corrected today an issue with the workshop upgraded into mason (for your current game : destroy the mason and build a new workshop).
Ok with FE 1.32 and my favourite mods (ROTM, SummoningUnits, ... AddFactionTrait may modify the Consulate but there's no big issue)
------ OPTIONS -------
Just delete the Volunteers.xml file if you don't want this :
The Volunteers unit design trait is unlocked with Cooperation. Gives Village and Outpost building abilities at Population cost. All players get it.
Just delete the Fortifications.xml file if you don't want this :
The fortifications system is modified for all players in the game
- All players can build Wooden Wall / Hedge Wall in the 3 kinds of cities.
- Wooden Wall & Hedge Wall are upgraded (more troops + unit bonuses) and their AI priority is increased. Only the Fortress city type can build Fort / Castle buildings, which are also upgraded (more troops + unit bonuses)
Just delete the Outposts.xml file if you don't want this :
High Towers, Stables and Consulates outpost upgrades see their AI priority increased (and Consulate building cost is decreased for All players)
-------------------------
I guess you understood that I can't speak a good English. That's why support will be very limited.
