About Mare Nostrvm

De Proelio Navalis is here! Mare Nostrvm is a strategy game by the developer of Qvadriga, and it is set during the turbulent war galleys era, when the civlizations along the Mediterranean Sea started to extend their ambitions towards new lands.

From the dawn of history to the Roman Civil Wars, from Iberia to Cyprus, revive the ancient naval battles of the Mediterranean. 24 historic naval battles, including Salamis, the final defeat of Xerxes in Greece, and Actium, Downfall of Antony and Cleopatra.

Choose between fourteen ship types, ranging from the small and primitive penteconter to the powerful decares and wage war in historic naval battles. Ram enemy ships, board them, or make use of your on-board harpax to make their encounter with Neptune the last!

Squadron system with chain of command, the ships needs to be under command to be able to receive orders. Admirals and commanders have special abilities and a squadron range, lines of ships could be arranged out of this range to give command to all of them. Gameplay includes crew fatigue, atmospheric phenomena like fog, rain and a variable wind system and special rules for treasure ships, local command, plague, anchored ships and transports.

Naval Squadrons employ real tactics of that time, and the WEGO system will force you to think three moves ahead of your opponent. Multiplayer mode allows multiple historical and skirmish battles to be played by two players using Slitherine’s easy to use PBEM+ system.

FEATURES:


- Classic WEGO system. Plan the actions first, then execute and view a simultaneous turn resolution
- Battle AI adapts to the tactical situation and the historical settings
- Configurable skirmish battles allows choosing of map, size, wind and opposing sides, using a point buy system
- 14 ship types, from the swift penteconter to the massive deceres, equippable with devices like engines, towers, harpax, corvus, rodian firepots or sails
- Historical tactics and maneuvers, depending on the situation and the ship type. Ram, rake oars or grapple and board. Arrows, artillery and fire

This is a GREAT lil pocket game straight out of the mid 80s!! cough [Ram Speed] I played this for a couple oh hours an it was really fun to decide how to customize my ships, with larger crew, siege engines, extra marines! spiked boarding blanks, fire pots etc. In my battle i was out numbered by 11 Triremes. My ships were larger an had more crew so i captured several enemy ships an turned um on there former owners! Thirty minutes later i had fought to a draw, the battle was dynamic interesting an really a lot of fun. I've been looking for this game for 15 years an i am oh so glad to have finally found it! Create your fleet an send thous pesky bad guy ships to Davie Jones's locker!

This game fills a unique position, as there really aren't many games on the market which let you tactically engage with the galley warfare of the ancient Mediterranean, even though these tactics are some of the most interesting battles of the ancient world, and the fundamentals of the strategy aren't that hard to understand. I wouldn't pick up this game at full price, as it has pretty limited ambition, but at 5 USD, it's a good deal if you are an ancient history fan.

I love that this exists, I would describe it as Combat Mission but for ancient naval warfare. It has command radii like CM, WEGO, 60-second turns, you can fast-forward to get through boring/uneventful parts of a battle. I enjoyed playing while listening to a podcast as a way to relax. Learning about ancient naval warfare is very interesting, these units are nothing like land warfare units you may be used to from Combat Mission.

Flawed but fun for the right kind of player. The ability to get ships stuck in between hexes, and overly long WEGO turn times make this game even more chaotic and uncontrollable than it arguably needs to be. That said, it's got charming, crisp and legible graphics and UI, lots of fun chrome (raking oars, setting ships alight, boarding, ramming, rams getting stuck in enemy ships, sail mechanics, etc etc) and there really is no other hardcore wargame on PC depicting the era, at least not in the last 30 years...
