Imperator: Rome Patch Notes - Marius Update 2.0 Reworks Military System

Imperator: Rome’s long-awaited Marius Update 2.0 goes live later today, its patch notes revealing a reworked military system, redesigned interface, and much more.

The Marius Update 2.0 marks a significant step in Paradox’s efforts to redeem Imperator: Rome. At launch, the grand strategy game divided fans due, in part, to its overreliance on “mana”, which gave ruling a nation a rather artificial feel. Subsequent updates kept addressing various issues, 2.0 giving the game a makeover that aims to make the UI a bit more lively while reducing the amount of clutter.

Here are all the changes and additions that you can expect when Imperator: Rome’s Marius Update 2.0 goes live later today, as detailed by Paradox in the full patch notes:
