Assassin’s Creed: Altaïr’s Chronicles is a video game released for the Nintendo DS, Android, iOS, webOS, Symbian, Java ME and Windows Phone. It is a prequel to the 2007 video game Assassin’s Creed, developed by Gameloft Bucharest and published by Ubisoft. It was released in the United States on February 5, 2008. It features two new cities, Tyre and Aleppo; and the three original cities, Jerusalem, Acre, and Damascus; but does not include Masyaf. Unlike the original Assassin’s Creed, the game is not told through the perspective of Desmond Miles, but rather the perspective of Altaïr Ibn-La’Ahad, although the menu screens do take place in the Animus.
1190 AD during the Third Crusade, Crusaders clash with Saracens for control of the Holy City, Jerusalem.
Altaïr is tasked by Al-Mualim to retrieve the Chalice. It is said to have the power to unite all factions and end the Third Crusade in victory for the side that possesses it. However, the Chalice is too powerful and must be found and destroyed.
The assassin, Altaïr, begins his journey at Damascus, where he learns that the Chalice is kept in the Temple of the Sand and that Altaïr needs three keys to enter it. Altaïr obtains the first of three keys in Damascus, then heads to Tyre for more keys.
Arriving in Tyre, he learns that Roland Napule is head of the hospital. Altair infiltrates the hospital and gets the second key from a prisoner of Roland, an old man who has been to the mysterious temple of the Chalice.
Altaïr then travels to Jerusalem, learning that the Templar leader, Basilisk, has the third key. The king is going to have a party somewhere soon. He finds out the location of Villa where the party is about to begin, infiltrates it and encounters Lord Basilisk for the first time. After a battle with him Altair gets the key, but has no time to kill him.
Later in Jerusalem, Templars attack an assassin agent, Hazad, and steal the map to the desert temple. Altaïr chases them to their tower. After making his way through, Altair finds the way to the tower and its Master, an assassin-like figure who is actually a high-ranking Templar. Altair fights his way through the tower, and finally reaches the Master himself, kills him and takes the map.
Altaïr then proceeds to the Temple of the Sand, where the Chalice is probably kept. There, he finds an empty chest and Lord Basilisk, who hints that the Chalice is in fact a woman. Basilisk taunts him, and Altaïr runs back to Tyre.
In Tyre, Altaïr pursuits Basilisk and finally agrees on a deal: Basilisk’s life in exchange for information. Basilisk reveals that the Chalice is in Jerusalem, and that the Templars are sieging Acre and are going to poison the water to quicken the siege.
Altaïr journeys to besieged Acre and helps the city by fighting off attacking Templar soldiers. He then goes to Jerusalem, where he successfully rescues the Chalice from a group of Templars. Altair identifies the Chalice as Adha, the woman he knew and liked before the events of the game. From her, he learns that the Templars have paid off Harash, the second-in-command of the Assassins.
Altaïr plans to attack Aleppo, the assassin fortress, kill Harash and run away with Adha, but after making his way through Harash’s assassin guards and killing him, Adha is kidnapped by Basilisk and taken to their port in Tyre.
Altaïr fights through the Templar knights and kills Lord Basilisk in one final confrontation on his ship. But Adha is on a different ship, which escapes before Altaïr can catch it.
