O Cerco de Lisboa, 1147 [The Siege of Lisbon, 1147]

The year is 1147. The troops of Afonso Henriques and the crusaders have been besieging Lisbon for over two months, but the Muslim garrison remains firm within the walls. In the Christian camp, an old inhabitant reveals a crucial secret: a house leaning against the walls hides a corridor that leads to a secondary gate of the city. If this gate is opened, it will create a breach for the conquest of Lisbon. The mission is risky and time is limited—the inhabitants can return at any moment. Your mission: enter the house, find the hidden mechanism, and open the gate before it's too late. The fate of Lisbon depends on you.
