In Narbacular Drop, the game that Portal was based on, you could fire portals through portals, but I like the explanation by Cormeh as to why this doesn't work.
OMFG he wrote the Skullmonkeys song!?!? I ****ING LOVE that song! I love it enough to have known all the words for the last 8 years. This guy is brilliant!
Fair enough. But it seems to me that half life is, like all fiction short of Terry Pratchett and South Park, a collection of cliches, which only work when handled with respect and in the right combination. Alien invasions? Assimilation? Portals to other worlds? Eccentric scientists? Gun-slinging...
It was her intention for you to destroy her morality chip, so I believe her declaration of deploying a "surprise" was the first step in her bluff and reverse-psychology scheme (the one to trick you into incinerating the chip).
I'm always disappointed by the lack of multiplayer cooperative modes in modern FPSs, and while I acknowledge that such a mode in the Half Life franchise is neither a good idea nor a workable one, imagine the following setup for a multiplayer game:
One player has a portal gun and no weapons or...
... Are you serious...? I enjoy trying to come up with elegant theories to incorporate every available piece of data - even though I doubt that the truth will be in any way elegant - and seeing these theories tested in a setting like this. I find it incredibly fun, whatever the subject; game...
Huh? I'm not referring to EpiTwo at all - I mean the portal storms that marked the combine's initial invasion. They were granted a glimpse because of the resonance cascade, perhaps enough to steal the BM technology to use later when they invaded the earth.
I'm suggesting that they used AS and BM tech to get to present day Earth. Though why they wouldn't use it while on Earth again eludes me. They do have some form of portal tech, which maybe what present day tech became thousands of years later.
Admittedly that's my major problem with it too. G-Man seems to be so much more mysterious and powerful than he is presented in this theory. So here's a better one - GLaDOS made CJ immortal and the G-Man who sabotages Black Mesa is in fact the several thousand year-old G-Man with improved...
Chell is the mind of the Combine, following GLaDOS's test where she proved she could correctly wield portal technology. Although GLaDOS said she erased that iteration of Chell, she lied, and in fact installed it in her androids, that later, perhaps thousands of years later, became the combine...
Chell will be referenced in Ep3 when it is revealed that she is G Man's (a.k.a, the insane mercury-poisoned CEO of Aperture's) daughter, and also the AI script used to power combine soldiers.
