Creative Assembly has announced that Empire: Total War will be getting some nice updates in upcoming patch.
Existing units that are currently only available to certain troops, will be made available to others along with changes to uniform and attributes.
Basically, as Kotaku pointed out, Dutch and Swedish troops can now access Hussar units and individualize versions of standard units like changing the reload times and morale.
The Russian Grenadier will be the newest introduction to the game, and along with ten unique replacement units and four existing units ‘unlocked’ for other factions – this brings the total amount of new content to 15 units across factions.
These units are free and will be released via Steam. Extra details and a release date are expected soon.
