Assassin's Creed: Bloodlines is an action-adventure game for the PlayStation Portable (PSP). The story takes place between the events of Assassin's Creed I and Assassin's Creed II, following the journey of Altaïr Ibn-La'Ahad as he hunts down the remaining Templars who fled to the island of Cyprus.

The game features classic Assassin’s Creed elements like stealth, parkour, and sword combat, adapted for the PSP. While the gameplay is simplified compared to the main console versions, Bloodlines offers a solid portable experience with a focus on exploration, assassination missions, and uncovering the Templars' plans.
