About this game
Crusades: Book II
Continue the struggle for the eastern Mediterranean in Crusades: Book II, a tactical medieval wargame covering the wars that followed the failure of the Second Crusade and the long contest that led to the Third and Fourth Crusades.
Beginning in 1149, the game follows a period of shifting alliances, fragile Crusader forces, and increasingly ambitious campaigns that reshaped the balance of the region. From the defeat at Inab and the rise of Nur al-Din, to Saladin’s victory at Hattin, the struggle for Jerusalem, the great operations of the Third Crusade, and the shocking diversion to Constantinople in 1204, this is an era defined by endurance, reconquest, siege warfare, and grand expeditions strained by distance and logistics.
Take command in Crusades: Book II, where 40-meter hexes and 10-minute turns place you in control of armies fighting across the Levant, Anatolia, and beyond. Storm fortresses, hold vital routes, defend ports, and fight major battles.
Command the Rival Armies of the Later Crusades
Recreate the campaigns of the later Crusading era from either side of the conflict.
Lead the Crusader Alliance, built around:
Armored knights and lance cavalry
Infantry armed with sword, spear, and axe
Crossbowmen and bowmen
Sappers and siege crews
Ballistas and other engines used to force fortified positions
Or command the Anti-Crusader Alliance, fighting with:
Fast cavalry able to strike, harass, and disengage
Horse and foot archers armed with powerful recurve bows
Spearmen and swordsmen
Onagers and other siege weapons used to break strongpoints and resist invasion
The historically accurate Order of Battle captures the changing military character of the 12th century: Crusader armies built around shock action, fortified defense, and siege assaults, facing opponents whose growing strength lay in mobility, missile fire, regional coordination, and the ability to concentrate force at decisive points. The result is a broader and more developed battlefield than Book I, shaped by reconquest, counterattack, and increasingly large-scale coalition warfare.
A Wider War of Sieges, Routes, and Reconquest
Crusades: Book II expands the conflict beyond the foundations of the Crusader states and into a broader struggle for dominance. The frontier is no longer a story of sudden conquest alone, but of repeated campaigns to seize, defend, isolate, and relieve the strongpoints that control entire regions.
Fight across battlefields where:
Castles, ports, and walled cities anchor strategy
Roads, crossings, and supply lines are vital
Field armies must cooperate with garrisons, fleets, and relief forces
Crusades: Book II captures the military character of the period through major sieges, open battles, raids, marches, relief attempts, and desperate defenses. Siege warfare plays a central role, with medieval engines and assault methods helping decide the fate of key strongholds and cities.
From Inab, Harim, Montgisard, Jacob’s Ford, Hattin, Acre, Arsuf, and Jerusalem to the storming of Constantinople, Crusades: Book II recreates an age in which the fight for the Holy Land became part of a far larger contest stretching across the eastern Mediterranean.

A Free Expansion for Sword & Siege: Crusades, Book II
We are pleased to announce the first free expansion pack for Sword & Siege: Crusades, Book II. This new pack adds a fresh campaign and 10 additional standalone scenarios, expanding the scope of the Third Crusade beyond the historical path taken by Richard the Lionheart and into the realm of plausible medieval what-if warfare. Much had changed since the First Crusade ended with the creation of the Kingdom of Jerusalem in 1099. For the people of the Levant, war became the inheritance of that success. There were periods of quieter conflict, truces, and even limited cooperation, but peace was rarely more than a temporary pause. Edessa, the first of the Crusader states to be established, was also the first to fall. Its loss helped call the Second Crusade into being, but that expedition failed to restore the county and failed again before Damascus.The surviving Crusader states, led above all by the kings of Jerusalem, continued to look for security through expansion. Egypt became one of the great prizes. Weakened by internal corruption and mismanagement, Fatimid Egypt drew the attention of both the Kingdom of Jerusalem and the Zengid rulers of Syria. Control of Egypt might have secured the Crusader position in the Levant. Instead, the contest helped prepare the way for Saladin and the rise of the Ayyubid dynasty.Over the following years, Saladin consolidated his power, uniting Egypt and Syria into a force capable of threatening the Kingdom of Jerusalem from more than one direction. That danger became catastrophic after the death of Baldwin IV, the Leper King, and the accession of Guy of Lusignan. In July 1187, Guy led the army of Jerusalem to disaster at the Horns of Hattin, where Saladin destroyed the bulk of the Crusader field army.Jerusalem followed soon after. Under Balian of Ibelin, the city mounted a determined defense, strong enough to avoid the massacre many feared and to force a negotiated surrender. Yet with Jerusalem lost and the Crusader army shattered, it see...Read full article on Community Announcements (Wargame Design Studio)Patch NotesOfficial
