Gamers excited for the fan-made prequel to Portal 2, titled Portal: Revolution, faced a delay as the game by Second Face Software, which was set to release on January 5, is still waiting on a review from Valve. The ambitious mod promises over eight hours of new gameplay with 40 test chambers, adding an almost standalone-game experience to Portal 2. The developers explained the delay with Valve's longer review times during the holiday season, reassuring players that the game is ready to launch as soon as it gets the green light. For Portal enthusiasts, this expansion of the Portal universe is expected to challenge players with new mechanics that build on the familiar gameplay from the original titles. The requirement to access this prequel content is ownership of Portal 2, which is currently discounted on Steam until January 11.

When can players expect the new Portal: Revolution mod to release?

The exact release date for Portal: Revolution is still unconfirmed, pending Valve's review. Once the review is complete, the developers will announce a revised release date. Players are encouraged to follow updates for the latest information regarding the launch.

Originally released in April 2011, Portal 2 is the critically acclaimed sequel to 2007's Portal, both developed by Valve Corporation. They are puzzle-platform games that center around using a portal gun to create linked portals and solve complex puzzles. This fan-made prequel, Portal: Revolution, is set between the events of Portal and Portal 2 and aims to challenge players with even more intricate puzzles and gameplay, carrying forward the innovative and engaging mechanics which have become synonymous with the Portal series.
