Portal Stories: Mel

Portal Stories: Mel is a modification to Portal 2.

Story
An Aperture Science test subject named Mel arrives at Aperture via train in 1952. Cave Johnson tells her that she will be testing the Extended Relaxation Vault, and tells her she will be asleep for a few minutes, or at most an hour. After going into the vault, something goes wrong, and she is indefinitely put to sleep. Later, far into the future, she is waken up by a voice pretending to be Cave Johnson that is trying to convince her it is 1952. It tells her to pick up a Portal Gun to participate in a "new test." After a few tests, he decides to stop the act, and reveals he isn't Cave Johnson, and they are in the future and stuck inside of Aperture. He is actually a core named Vergil who is stuck at the bottom of Aperture, and needs your help.

Mechanics
Portal Stories: Mel's mechanics work similar to Portal and Portal 2.
