Portal: Revolution is the latest installment in the iconic puzzle-solving dystopian future game Portal. While this newest game may not have been made by Valve, it is endorsed by the company - and for good reason.
Portal: Revolution is not a full game but a mod that introduces players to new characters as well as a fresh story that takes place between Portal and Portal 2. Set 30 years after the events of the first game, and happening after an intense fight where the protagonist from the mainline Portal games blows up the antagonist GLaDOS, you are woken by a robotic personality sphere named Stirling in the Aperture Science facility.
