Portal will get a massive story modification

This story mod will add a new scenario to the game. It will be set in the period between Portal and Portal 2, and the protagonist will have to restore the Aperture research center.

The developers promise 40 new puzzles, which will take about 5-7 hours to complete. Portal: Revolution mod will be released on January 5, and will be available for free. And now you can add it to your Steam wishlist.
