Hey to cut a long story short i got bored of being the NCR's mission slave so i just went to the leigons camp and killed everyone including ceasar and got the platinum chip and gave it to Mr.House, he updated the robots and told me to go back to the camp, to open the secret door. But he didnt give me the chip back and i have no way of getting on with the mission and opening the door!. Can anybody help me?
