Castleon is a turn-based castle builder strategy game. Your goal is to either survive for a certain amount of turns, or conquer all the enemy Lords.
Build walls and towers of wood and stone! Put traps and snares, dig moats, raise mottes. Construct an impenetrable fortress that will stand the test of time!
Man the walls! Unleash arrows, bolts, rolling logs, boiling oil pots, pitch and rotten carcasses upon thine enemies! Make them eat cold steel! Destroy their catapults and battering rams! Push back ladders! Dismantle their siege towers! Survive the Third Crusade!
With a massive tech tree, 5 different religions, many different types of policies, 16 criminal abilities, randomized lord relations, random events, and 6 difficulty levels, no two matches will be identical in Castleon! Position of your castle is not predetermined on maps and you get to pick and customize every aspect of your kingdom!
Over 70 different buildings, walls, towers and traps
Many different units - from the basic Spearmen and Archers to the powerful Templar and Teutonic Knights, hasty Horse Archers, elusive Assassins, mighty Varangian Guards.
