hmm, does the mirror in metal gear solid in the womans restroom in the nuke storage count too? (im not 100% sure, but it should be a "full working" mirror too)
Mission Impossible on the PS is another game with them mirrors. I remember that GTA: San Andreas didn't have true mirrors, equip a rocket launcher and aim up and down while facing a mirror, the "reflection" doesn't show yourself pointing the weapon up/down...
