Portal Stories: Mel

Portal Stories: Mel is one of the most popular fangames for Valve's 2012 puzzle game, Portal 2. Set between the events of Portal 2 and Portal 1. The story follows Mel, a 1950's Aperture recruit who finds herself woken up an unknown amount of time after her experiment goes wrong.

Trivia

 * Some links can be seen between the existing characters in Portal Stories: Mel and the dynamics presented in Portal 2, with Mel replacing Chell, Virgil replacing Wheatley, and AEGIS replacing GLaDOS.
 * Although Mel is similar to Chell, she is not based off of her. She is based off of an unused Portal 2 co-op character with the same name.
 * Portal Stories: Mel shares the same universe with Meet the Cores, a fan-made video series by Harry101UK, aka Harry Callaghan. It is, however, non-canon to the actual story of Portal. Harry Callaghan also happens to voice the Rainbow Core and AEGIS.
