Assassin's Creed

During the majority of cut scenes while you're playing as Altair, you will sometimes see the screen 'glitch'. You will see a bunch of hexagon-shaped molecule diagrams flash quickly on the screen.

• Pressing any button will make the scene cut to another camera angle. These are the glitches.
• Constantly tapping any button during every cut scene will make sure you hit at least 85% of the glitches.
• If you get every glitch, this achievement should unlock during the cutscenes for the 8th assassination
