You step into the role of a generic test subject who is thrust into a gauntlet of challenges by Aperture Science, the creators of the Aperture Science Handheld Portal Device (ASHPD). They challenge you to think beyond the normal laws of physics and use the ASHPD to accomplish the impossible.
Remember: All test subjects for Aperture Science will be subject to... Cake... at the conclusion of testing. That is all.
