If you played Portal 2 and found one of the secret easter eggs, a quartet of singing turrets in one of the ventilation shafts, you probably wondered why they were doing that. Well the folks at Aperture Laboratories have the answer to that mystery in the form of a comic. The reasoning behind having a singing Turret is a bit preposterous but then again what do you expect from a lab that thought it was a good idea to give robot with a brain full control of it’s facilities and poisonous gas. Check the comic over on the Portal 2 site.
