I read somewhere that there are 2 endings. Don't know if its true. But the ending i got was
after destroying GLaDOS, she blew up and I got transported to the parking lot, apparently dead or just laying down, or since Chell is an android, her head popped off, I dont really know.
if you are truly dead/dying at the end when you're in the parking lot, that blows ...I wrote Gabe asking about that (no reply so far..), as I think it would suck badly if that were the case :frown:
