Just finished it. As was the case in Episode 1, I had no idea that the ending would be so very abrupt. Although I'm glad we once more got to see large scale environmental stuff going on in the distance. I'm really glad this time around that we got to experience the great outdoors a bit and had large scale maps that really covered some noticeable ground, as opposed to Episode 1 which was block after block after block of bombed-out City 17.
Also, did anyone take note of Kleiner's mention of Black Mesa's competition, "Aperture Science"? I love how this game and Portal comliment each other so well. I'm curious though as to when "Portal" takes place. There's no human or Combine personelle in the whole thing, which may suggest it was abandoned, but then why is the protagonist still there? Or perhaps the facility was refurbished and made to be 100% automated by GLaDOS by the Combine. The facility's projectors still show images of their competiton with Back Mesa, but still I'm pretty sure I've seen a random poster of Doctor Breen somewhere. Though maybe back then he was just the face of Black Mesa.
It all makes me excited to see how Episode 3 plays out. I really hope we either Freeman runs into Portal's protagonist, or at least the Aperture Science Enrichment Center, and maybe the portal gun, if only for a little while. Maybe GLaDOS will still be enough alive to give Gordon some tips, commentary or dis-information.
