About Diplomacy is Not an Option

✦ AI summary

Build and defend your castle against overwhelming waves of thousands of enemies using fortifications, armies, economy management, and magic across multiple game modes and procedurally generated maps. Master the physics-based warfare, resource chains, and strategic base-building as you navigate a dark medieval fantasy where your only path forward is total victory.

Diplomacy is Not an Option is a base-building RTS where your task is to fight against vast hordes of enemies. Over 25 THOUSAND of them will storm your castle on procedurally generated maps. To survive, you must build fortifications, raise armies, master engineering, economy, and even magic (the active pause spell included).Experience warfare on an entirely new scale in the 4 game modes: Endless Mode, Story Campaign, Challenge Mode, and Sandbox Mode. Additionally, you've got the Map Editor to create your own scenarios in the medieval fantasy world of Diplomacy is Not an Option.Your king is an egocentric pig who has driven the country into an economic crisis with his mindless money-spending. This problem, however, is mostly yours. After all, this is your feud, where peasants are revolting because of unfair taxes.You can suppress the rebellion, or you can join it. But it's a long road to the end goal. A road on which you will encounter the mysterious tribe of Sarranga and the Undead who worship hard-rock music. No matter which faction you join, casualties will number in the thousands. And siege weapons will mercilessly blast crowds of your enemies. And legions of loyal troops will give their lives for the success of your mission. While admittedly tongue-in-cheek, the laws of physics are still deadly serious in Diplomacy Is Not An Option. Every arrow, catapult stone and enemy launched skywards is physically modeled, making for a tactile and coherent battlefield. Just make sure your troops have towers to shoot from and clear lines of sight, or you might find your best-laid plans embarrassingly blunted by your own fortifications. Consider your gates, your lines of advancement and retreat. Create kill-zones and fall-back positions. You will need to take an active role in combat to get the best from your men. Even under siege, never forget your castle was built on the backs of the peasantry. Defend your people, and they’ll serve you well. Engage in agriculture and farming, or food can become scarce, and your soldiers can starve on the battlefield. Build houses, bury fallen soldiers and peasants to prevent plague, and treat the infected when death comes knocking. If you do not care for your people you may soon find yourself overrun with the most unpleasant troubles. Like empty stockpiles, unrepaired walls and running dry barracks… or be overrun literally with swarms of zombies. And no lord wishes to see zombie apocalypse in the backyard of his castle, right? A functional army requires a functional economy to support and feed it. Food, Wood, Stone, Iron, and Gold are the foundations of your city’s economy, and you will need to watch your supplies carefully if you are to meet the advancing foe in a timely manner. Gather resources, choose your storage locations, plan your expansions and upgrades with care. The enemy will not cede their lands willingly, and unprotected civilian expansions will have consequences of falling prey to the hostile incursion. Trade, via the impressive merchant dirigible, bringing emergency supplies of food to feed the men, or stone to rebuild the walls. Can you strike the balance between greedy expansion and security? If life gives you lemons, make lemonade. If you’ve inherited a cursed kingdom, why not master the dark arts ? Sturdy castle walls will protect you from most ordinary threats, but in Diplomacy Is Not An Option you're also be battling undeads. So why give them a monopoly on magic ? There is a dark history of tainted power that stirs zombies and traps wayward souls. On the lighter side: it can also be used to call down really very big fireballs onto your enemies. So enjoy that too. Build magical monuments, harvest soul crystals and give a try to a maniacal laugh as searing magical beams tear through your foes and summoned ghosts to chase down the stragglers. The game has been designed with freedom as a core concept. Go beyond the campaign and crush your foes as you see fit in Endless Mode, Sandbox Mode or Challenge Mode. Develop your own personal strategies on procedurally generated maps. Go heavy on walls early, build large armies of cannon-fodder, or pursue the macro game of greedy growth and costly investments. Play battles in real-time or use pause constantly to keep everything in your hands. Will you be able to stand on a par with the most acclaimed generals in the world, like Joan of Arc and Genghis Khan? Finding which style grants you the most success is up to you.As in real life, stupidity and greed lie behind most problems, but here it is far too late to talk it through. You have no recourse to resolve this peacefully. At this stage: Diplomacy Is Not an Option!

At point of review, im.only six hours in. I can alredy tell that this will become one of my most played games. It feels very similar to fortress crusader from way back when with the building. Mixed in with the enemy count of they are billions. Playing trough the campaign, the cut scenes are hilarious, we play as a lord of a castle that we get to name. And your advisor who is my favourite character ("pupulta", is what he always says when adresing the lord, it has become a new vocal stim for me). The recourse system is simple, yet it holds a fair bit of complexity. There is wood, stone, iron and gold coins. Housing and population can technically be counted in that too. But it has that positive feed back loop akin to factorio. In one mission you have to build boats, my defences weren't up to par and the pesantry broke through and destroyed one of the boats as it finished. This happened 3 more times. I finished that boat and loaded what I needed to complete the mission as another wave was at my wals and overwhelming my defences yet again. I completed the mission and on the victory screen you could see my castle get stormed by the pesantry. All of that was on the medium difficulty…

Fun and exactly what needed to scratch that base defense itch. Plus the devs seem cool, plenty of updates.

Very engaging, with different factions and a multi-furcating campaign

First impressions are very, very good. It has a strong Stronghold vibe and you feel like you are defending Helm's Deep or Minas Tirith. I'm not a fan of micromanaging your troops around the map to destroy the tents and collect stuff. The cutscenes between missions are bad and way too long.

Amazing game It is kinda hard though but once you get used to it it becomes peak and It takes an hour to an hour and a half to beat each campaign level
