The Half-Life and Portal timeline is long and complicated. Although these stories are set in different locations on Earth, they connect over the years. From Black Mesa's early years and their competition with Aperture Science, to the fall of Aperture and GLaDOS' attempts to keep The Combine out of her facility. This timeline has many important events. In this video, I explore the whole history and story of Half-Life and Portal. Although Chell and Gordon Freeman never meet, their actions have a huge impact on Aperture Science, Black Mesa and the multiverse.
