You play as an aperture science test subject, male, and you play though a new 20 levels that are harder and more punishing than the original portal levels. You play an active role in destroying a few of the test chambers, including much, much more BTS areas than before. In the end you face some sort of boss battle and I'd rather not reveal the ending 
**Story B:**
You play as an indipendant inspector who has been sent to aperture science against their insistance that their reserch is all legit. you are greeted by a rather excentric scientist who shows you around before a terrible accident occurs (think Borealis?), the lab is thrown into chaos with scientists runing about everywhere trying to sort stuff out, you of course have no clue what is going on. The scientist showing you around tell you where you can wait thats safe (his office or something) he gives you directions and once you get there he does a video call thing to you and he tells you to stay put but of course you cant resist the temptation of looking around and you work your way into a huge almost empty chamber with scaffolding and something in the middle, you can't resist turning on the power as its all dark and nothing much seems to happen. the test chambers are accesible from this large silo... you're working backwards through them facing new challenges in doing them in reverse as you work further underground. the further you go the more 'awake' the prototype GLaDOS unit you turned on becomes, it makes things harder for you as you go through the level.
and I'd rather not reveal the ending of this one either.
yeah, story A was my original idea but with Username's aid we planned out story B. so story B sounds a lot more developed.
Opinions? thoughts? suggestions? Anyone want to write a propper script based on either of these ideas?..etc etc
