Aperture science. A story that is happy, sad, heartbreaking, and probably some other things. But one thing the story will remain, a mystery. Until now. I am going to tell the story of Portal. This story will not just include the main games, but with 14 unofficial titles included. This story was very difficult for me to complete. But it's done now. The mods include Aperture Tag, portal project alpha/beta, portal skyline, blue portals, and many more. So sit back and enjoy the timeline that can put even the fnaf and Zelda timelines to shame! This is Portal FPS.
