CastleOn

CastleOn is a turn-based castle-building strategy game. You can win by surviving for a set number of turns or conquering all enemy Lords. Choose and customize your kingdom, including your castle’s position on each map, then build defenses, manage your realm and fight through sieges.

Build and defend

Construct wooden and stone walls and towers, set traps and snares, dig moats and raise mottes. During attacks, you can man the walls and use arrows, bolts, rolling logs, boiling oil pots, pitch and rotten carcasses against enemy forces. Destroy catapults and battering rams, push back ladders and dismantle siege towers.

The game includes over 70 buildings, walls, towers and traps, along with units ranging from Spearmen and Archers to Templar and Teutonic Knights, Horse Archers, Assassins and Varangian Guards. Research over 90 technologies, each of which changes how certain buildings or units function.

Rule your kingdom

Manage diplomacy with over 50 historical Lords who reigned in the second half of the 12th century. They include Richard the Lionheart, Saladin, Henry VI, Baldwin the Leper King, Isaac II Angelos, Stefan Nemanja, Kulin Ban, Knut Eriksson, and the Alfonsos and Sanchos of the Iberian Peninsula.

A large tech tree, randomized Lord relations, random events, multiple policies and six difficulty levels add variation between matches. You can also use 16 criminal abilities to gain bonuses at the cost of corruption; a corrupt court reduces the effectiveness of buildings and resource gathering.

Faith and campaigns

Choose from five religions, each offering 10 passive bonuses based on your peasants’ faith. Religion is optional and can be enabled or disabled in the menu.

Fight across the Holy Land, the Balkans, the Iberian Peninsula, Scandinavia and central Europe. The game includes over 50 Skirmish maps set around the locations of famous castles, as well as historical campaigns featuring real battles and custom victory and defeat conditions.
