Assassin's Creed Director's Cut for PC looks to follow the success of the critically acclaimed and worldwide console hit, Assassin's Creed, which has sold more than five million copies worldwide since launch. PC players will experience four brand-new exclusive types of investigation missions, providing even more ways for players to explore the various locations of the Third Crusade. Players will assume the role of the main character, Altair, whose purpose is to stop hostilities by suppressing both sides of the conflict while learning the art of becoming a master assassin.

The four new investigation missions are an addition to the five original ones found in the console version; meaning, players will never have to complete the same (investigation) mission twice before moving on to assassinate their next target.

Rooftop Race Challenge: Upon meeting an informer, the player will have a set amount of time to reach a second informer. The reward for reaching the second informer on time will be information on the mission target.

Archer Stealth Assassination Challenge: The player will need to assassinate all archers, without being seen, in a certain zone to help other assassins carry out their missions.

Merchant Stand Destruction Challenge: An informer requires the player to break a set number of merchant stands. The merchants have ties to Altair's target and their activities must be stopped.

Escort Challenge: The player needs to securely escort a fellow Assassin from point A to point B.
