portalportal-2portal-series
I've looked at several videos of Portal 2 and am interested in buying it. The problem is that I've never played the original Portal, the first game of the series.
Should I play Portal before playing Portal 2?
She is Chell.
See here:
Although Chell's origins are unknown, she was most definitely among the people present during GLaDOS's activation in 200-, as GLaDOS locked down the facility after her activation, letting none escape, or be let in from the outside.
EDIT: Visiting aperturescience.com, you can learn that she is the daughter of Cave Johnson (CEO of Aperture Science) and that she was brought there on Bring Your Daughter To Work day.
"Clean out the skeletons" is likely not referring to actual test subjects in this case, but rather the English idiom of "having skeletons in one's closet".
The implication is that he is discovering all these things he didn't know about (or was otherwise repressing his knowledge of) for the first time.
However, it is Portal, so the possibility exists that Wheatley is actually being all too literal. In that case, the skeletons would be from the test subjects (or Aperture Science employees) that GLaDoS killed when she took over the facility. It's important to note that Chell was placed at the top of the "To Be Tested" list, and a list of who to test next gives no indication as to whether or not she was the "first" test subject post-takeover at all.
Best Answer
I think it's definitely worthwhile playing Portal first. I just started Portal 2 and would probably have been a bit lost without having played Portal first. There is almost no introduction to how the portal-gun and other stuff works in Portal 2 and there are a lot of references to the previous game.
It makes Portal 2 an even better game if you have played Portal.
