5.) Aperture Labs (Portal)
Do you know about the history behind Aperture Laboratories? Apparently, the company was spearheading research for the Counter-Heimlich Maneuver to ensure choking and started the Take-a-Wish program to give the wishes of dying children to healthy adults. Cruelty is definitely their business. What's unforgivable is the fact that they promise you cake and then lie about it in the end!
