Kane99 Posted January 16, 2024 Posted January 16, 2024 Of course, you must first own a copy of Portal 2 in order to play, but it's currently available for free on the Steam marketplace here - https://store.steampowered.com/app/601360/Portal_Revolution/ It just came out this month as well. It's a fan made mod that's essentially a new game. It is said to have 8 hours of gameplay wit up to 40 new levels or so. It's also said to be a prequel to Portal 2, so it takes place after the events of the first game.
