Description
Portal: Prelude is a mod for Portal released on October 10, 2008, designed to expand the game’s story by exploring the pre-GLaDOS era of Aperture Science. In other words, it serves as a prequel to the original Portal.
The narrative takes place before GLaDOS was ever activated. During this period, human Aperture Science staff oversaw the test subjects. Players take on the role of a test subject named Abby and are guided by various scientists through 19 extremely challenging test chambers, which are far more difficult and hazardous than those in the original game.
The mod is divided into 8 chapters and also includes 48 challenge maps and 6 advanced test chambers.
An official remaster, featuring RTX support, updated maps, and full voice acting, was released on Steam 15 years later, on July 18, 2023.
