Quick Links
While it’s the shortest section,Portal: Revolution,the game-sizedPortal 2mod, goes out with a bang through one final battle between the human and the other forces at work inside Aperture. You will need to use everything they’ve learned up to this point to get through the last two sections of this game.
While one of the easier sections, the final battle can be confusing, and it’s easy to run out of time given the number of tasks you have to complete in order. To prevent you from having to do so, just think about what has worked in previous chapters and apply it to Chapter Eight.
