The Black Mesa facility was apparently built over several decommissioned ICBM launching and testing silo complexes probably constructed during the 1950s, which was converted into a vast civilian institute for the research of almost every conceivable scientific discipline.5.2.9 Biological Waste Processing PlantĪ fast food outlet seen by Barney Calhoun in the Black Mesa Transit System.5.2.4 Area 3 Medium Security Facilities.I think it's like a Halo 3 ODST situation, taking place in between each other. Though I remember a theory as to the combine leaving because when, spoilers ahead, Eli gets killed, they gained his knowledge of portal tech through. I think portal 2 happens afterwards, either the combine leaving earth, a barren shell of what it used to be, or we win. I'm going to go ahead and assume this is when half life two takes place, and the episodes after. Kill glados, get dragged back down by the party bot, and ratman puts her in cryostasis for an unknown amount of time. Blah blah portal one happens, in the end, glados references how it's different outside, and how she's the only thing standing between us and them, or stopping them from getting in idr what exactly she said. Iirc chell and the ratman are the only two left, and ratman puts chell at the top of the testing list because her file says to not test her because she's basically won't give up. She trapped or killed the remaining workers and forced them to test for the new science initiative. Marc Laidlaw confirmed this original intention, correcting the erroneous 1998 date.įrom what I remember, aperture is abandoned once glados took over. However, the HL1 storyline is quite clear about it occurring in "200-". *An asterisk here as the Aperture Science timeline denoted GLaDOS's activation as occurring in 1998.

This was an intentional time gap to distance the events of Portal from Half-Life. The only other time relation known here for certain is that Portal 2 takes place at least 50,000 years after the first, also indicated in The Final Hours of Portal 2. The Final Hours of Portal 2 states that it's sometime between HL1 and HL2, no more specific than that.

GLaDOS's cryptic words referring to an outside "them" suggest that the Combine's occupation of the planet is in full swing by then, but this still doesn't give an exact point of reference in relation to the events of Half-Life 2. When Chell is woken up to first begin her testing, it may have been days, months, or even years since GLaDOS took over the facility. The timeline states that GLaDOS was activated at Aperture several days before the Black Mesa incident happens in HL1.*īeyond that, though, there aren't any exact indicators as to what's happening in the outside world when the Portal games take place. However, outside references have given hints as to the game's time of occurrence in relation to Black Mesa. Within the Portal series, there are no explicit in-game references that precisely identify its date in the overall Half-Life timeline.
