Mare Nostrum Expansion Announced for Europa Universalis IV

Paradox Interactive has announced the latest expansion for Europa Universalis IV.

The new expansion is entirely focused on the nautical aspect of your empire, and is aptly named Mare Nostrum. Featured above, you can view the announcement trailer for the expansion.

Here’s the press release, via Paradox Interactive:

europa universalis iv 03-01-16-1

If you control the sea lanes, you control the trade. If you control the trade, you control the world. It all sounds so easy. But first you need guns and ships and men to man them. It’s one thing to protect your coasts, but another to project power beyond them. Are you ready to make the ocean yours?

Mare Nostrum is the new expansion DLC for Paradox Development Studio’s best-selling historical grand strategy game Europa Universalis IV. For those of you not up on your Latin, “mare nostrum” was the old Roman term for the Mediterranean – it means “our sea”, reflecting the Roman goal to dominate the sea to protect the food and riches that were rowed into its ports.

Mare Nostrum, therefore, takes its name from the major changes made to the naval game in Europa Universalis. For example, your coastal provinces produce sailors who will be needed to man and repair the warships and transports you have come to rely on. A new mission system for naval orders simplifies naval management, and the Barbary Coast nations of North Africa can now raid their neighbors for gold and sailor conscripts.

Other features of Mare Nostrum will include:

  • Condottieri: Rent out your soldiers as mercenaries to give an underdog a fighting chance while filling your treasury
  • Trade Leagues: For merchant republics, the power of the purse is amplified by creating economic and military alliances
  • Share Maps: Instead of waiting for the world to come to you, ask your friends if they have discoveries they are willing to share.
  • PLUS changes to diplomacy, subject nation management and much more, including the usual major patch that will be a FREE upgrade to all EU4 owners.

Mare Nostrum will be launching across major digital retailers, as well as the Paradox store.

    Can’t be the only one that thought of Mussolini upon seeing the title. :)

    Too bad EUIV has been ruined for quite a few expansions now.

    As a side note, does paradox ever run out of ideas for DLC? Christ the DLC for EUIV alone is about 4 times the cost of the base game, forget about CKII.

    I checked the Steam page and this looks like something I’d totally be interested in. But after looking at the list of DLC I’ll have to pass. That must be the longest list of DOC I’ve seen in my life.

    All the expansions have made the game less random, more realistic, and generally better. You must be mad it’s not as easy though I suppose.
