Graphics card: You must have pixel shader ver 1.1 or later to run portal.
Many reasons. Maybe the game is a little dusty, or there could be some scratches on the game.
yes you do other wise you wont have the right portal and you won't have the right game for the console
well, the puzzles, jokes, etc. are the same, however, the only difference is the ending. i wont tell you, in case if your interested in buying either one. but i will tell you, orange box probably has a better tie in to the second portal game :)
Maybe Im Not Sure If Valve Will If They Do Atlas and P-Body They Wont Be In It
You send a portal on a ceiling get on the machine with fan jump over you wont make it so then have a portal on floor .:P it is complicated so sry I cannot explain any better.
For many reasons some of which are provided in the related question
rpm went to zero cranks but wont start
Yes, once you beat a chapter, go to the main menu then click new game and select the chapter.
i dont think so because VALVe said that there not going to use old humor so there is a possibility that it wont be in the game how could a cake survive for hundreds of years after portal 1 unless the fridge still works but theres no sense crying over every mistake.........
There are different reasons why people want to work for a call center. Some reasons are the different shifts available or the ability to interact with a variety of people.
