UNLICENSED GAME
This game is an unlicensed version of Portal 2.
Portal Stories: Mel is a community made, free modification for Portal 2 based in the Portal universe. It tells the story of Mel, who meets a new personality core and faces an undiscovered threat to the Aperture facility.
1952, in the early years of Aperture: Science Innovators, Cave Johnson’s scientists experimented with whatever they wanted. Not everything worked as it should have though, but that wasn't going to get in the way of the progress of Science! Mel unfortunately took part in a faulty test called the Aperture: Science Innovators Short-Term Relaxation Vault, falling asleep for years. When she finally wakes, the voice of Cave Johnson tells her she needs to escape the facility by using a new device called the Aperture Handheld Portal Device.
