How does Portal fit into the Half-Life series? Exactly when relative to half-life, do the events from portal occur? Also, why, if they are close competitors, does Aperture’s research facility look so much nicer and more advanced than Blackmesa’s? And, in Portal, what happened to all the people? There are tons of chairs and desks and observation rooms, even a running powerpoint presentation, but not a single scientist. What happened to them?
Thanks to anyone who answers. Also, are there any official answers from Valve, or is it all just speculation?
