Forum:Killed mr house b4 i got the platinum chip back

i had to hunt down benny as he fled to the legion camp, got given the chip by cesar, then i killed everyone and got my guns back. then i left and gave the chip to mr house, and then instead of getting it back i forgot and just went and killed him. what am i suppose to do now to get the chip back. got no other game saves so potential game ruiner lol
