Players may unlock bonus weapons by syncing save data from the Assassin's Creed: Bloodlines PSP game with Assassin's Creed II on the PS3. Connect the PSP to the PS3 via a USB cable, with BOTH games running. Then, select "Connectivity" from the Assassin's Creed II options menu, and "Connect to PS3" from Assassin's Creed: Bloodlines. The games will evaluate each others' save data and unlock in-game weapons and bonuses based on the player's progress. A complete story-mode playthrough of Assassin's Creed: Bloodlines will unlock six weapons that will be stored at the villa.
