Legacy In April 2012, author Rob Swigart and Subliminal Games launched a Kickstarter fundraising campaign called "Rob Swigart's Portal (1986) Reborn" to recreate the world of Portal as a modern third-person adventure game. Some of the features set to be included were moving backward or forward in time through a simulation of the past and changing the character's appearance for different responses and reactions by virtual non-player characters.
