I am stuck on trying to find pandoras box. I am about to go to the upper level and it says i cant return without pandoras box. So where is pandoras box

First of all (although you already may know) God of War is one of the best games for ps2 (especially once you unlock the alternate costumes---pure bliss). With that out of the way, if by "upper levels" you mean the cliffs, then I might be able to give you a couple tips. First off, have you gotton both the green and red necklaces (sorry I forgot the names, it has been a while)? If you're on the cliffs part, it should be fairly straight-forward. Make sure you get both necklaces and please post again if you are somewhere else . I can probably help, just please be specific....I mean the temple of Pandora....nvm don't want to spoil anthing. Hope this helped
