Portal: Revolution Fingerprinter Achievement Guide
Below is a guide on each of the glass locations for the Fingerprinter achievement.
Chapter 1: Advanced Cube Mechanics
Most likely the easiest one out of the bunch. Hard to miss. Walk up and claim your prize.
Chapter 2: Conveyors and Ventilators
You’ll likely see it, but it’ll be out of reach behind a railing. You need to walk around, hop on a vent, and hug the wall to reach it.
Chapter 4: Power Switches
Look up by the switch to see your target. A simple fling from the wall will do to reach it.
Chapter 6: Vacuum Tube Examination
Simply jump towards it from the light bridge to leave a mark. Don’t worry, the cube will catch you on the way down.
Chapter 8: Finale
Out in the open, but very easy to miss with the ticking timer. I missed it twice in my search! You’ll need to do a little parkour on the server racks, but it’s nothing too hard. Only a 10 second diversion from your real goals.
