Half-Life & Portal: The Unified Theory

Caste, this is just...amazing. One of the most clear and well-written theories among us!
Everything you say is backed up with evidence. Even though I've been playing HL since 1999, I still haven't pieced together every tid-bit of information. Well done, kudos from me.

I did enjoy your linking of the Nihilanth to GLaDOS - I always thought the Nihilanth was sort of left after HL1..
Do keep going. I wouldn't worry about your English grammar. There are a few corrections, but, really, it's not necessary to point them out. We get what you're saying so it's cool.
Keep it up!!

Thank you, I appreciate it. I hope many people will know about this and read it. I have the same thread on blackmesasource and facepunch forums, later I will update it. It was very very difficult to write that theory, I was thinking about it and writing for a long time, it was rewritten from the beginning to end many times. The last thing I'm going to do are some fixes and polishing that theory.
The only reason why that theory was borned is when I saw GLaDOS for the first time in the first installment of Portal, I was amazed that GLaDOS has so many similarities with Nihilanth. Everybody knows that VALVe like to use their ideas over and over, then VALVe created GLaDOS and used some ideas taken from Nihilanth, but for me the main goal was to explain from the position of story how that character as GLaDOS can exist in Half-Life Universe, what was a major requisite to create it and so on. I wanted to make that theory fresh and very interesting by adding a Prequel story (that can be about a new player's character, an unknown hero who was in XEN long before Gordon Freeman and took the crystal, after that disappeared at the end of game like other main player characters) and making a link between Nihilanth and GLaDOS, for me this is the most interesting parts in that theory. I want to thank everyone on this forum, you guys helped to make that theory better, I red so many threads here and took some really useful ideas and material.

This is awesome, it makes so much sense. After all this time I never knew that the crystal used for the resonance cascade was stolen from Nihilanth's chamber. The link between Nihilanth and GlaDoS is really interesting

This dude should have his own website purely for these fascinating theories
Have you ever thought about like.. writing your own prequel, as you say? As a fan-fiction/theory kinda thing?

That's right, moreover the main difference between Half-Life and Portal stories is in Half-Life story there is a character who want to stop science [G-Man], in Portal there is a character who always doing science at all costs [GLaDOS], even in the end of coop mode her main quote was "You saved Science".
Post it, go ahead!

Of course, but I confined myself to write only this small part of prequel in this theory, to show that HL story has a good plot to make a prequel, I just gave a necessary direction how prequel should be created.



Update:
I just red the theory on reddit.com and people complain about poor reading and grammar. I don't know what to do, maybe someone will help me, who can responsibly and correctly improve/ fix some parts of the theory.

I'd be happy to correct it for you, but, in all honesty, you'll always come across people who can't write properly themselves complaining about your work. If I were you, I'd hold your head up high. These trolls find anything to scrape at. I don't mind constructive critism myself, but you always get those people who whine at you..

I enjoyed reading your theory. Works for me more or less )))
