Portal: Revolution is a 2024 puzzle-platform modification for Portal 2 developed and published by Second Face Software. Set in the Portal universe prior to the events of Portal 2, the player controls an unnamed test subject as she attempts to gain control of a device that will restore the Aperture Science test chambers to full condition. The player traverses the puzzle chambers using the portal gun. In addition to the standard mechanics of Portal games, the mod also introduces a gel cleansing shower, paired cubes that transport laser beams, and Pneumatic Diversity Vents that transport items.
Development of the mod began in 2016; the mod uses a custom version of the Source engine that introduces features that are "impossible in Portal 2" according to the mod developer. It was released on Steam for free on January 6, 2024, after being delayed due to approval difficulties. The mod's gameplay, graphics, and voice acting were positively received by reviewers, while the writing received mixed opinions.
