Hello everyone and welcome to another development diary for Europa Univeralis IV. Today we’ll look at a few of new features available for those with the Mare Nostrum DLC.Whether it’s 10 days or 10 years into a war, there are moments when you know deep down that there is no victory in sight. Currently you might have to wait for your enemy to siege down certain provinces and put your army at great risk before you are able to sign peace, or you are fighting another player who is more interested than your total destruction than simple terms. For these moments, we have added an Unconditional Surrender button.Upon offering unconditional surrender, all of your currently unoccupied provinces will fall under enemy control and your enemy will gain 100% warscore. Your armies in your own provinces will become exiled and unable to fight in future battles until peace is signed. For the recipient of an unconditional surrender, you will be alerted of your enemy’s surrender and from then on will be able to enforce any possible peace up to 100% warscore cost. If you do not sign peace, then after a couple months you will get Call For Peace giving you monthly war exhaustion which increases faster than normal. The peace you offer will automatically be accepted by the surrendering nation.For the time being, the AI does not offer unconditional surrender. They will however, gladly accept them.If you find yourself so busy crushing your enemies to the point of Unconditional Surrender that you have neglected to explore the world around you, Mare Nostrum also bring a new option to the table by way of the Map Share feature.Map sharing is a new diplomatic action. If you have good relations with a nation who has discovered land which you have not, you can request that they share their maps of a region with you. This will cost you a lump sum of 15 prestige of which 10 will be granted to the kind sharing nation. Colonizing nation are greedy and will not want to share but nations who share a common foe may be more willing to share.If asking nicely is simply not your thing, you can take the shady path and swipe the maps. It will require the Espionage idea group and cost a moderate amount of Spy Network points, but you will be able to steal the maps right from under their noses.Stay tuned for more information next weekMare Nostrum will be available on April 5th for €14:99
