i got the platinum chip for Mr. House and i gave it to him, but now there's a problem, i'm trying to do the quest The House Always Wins II(part 2) where you use the platinum chip to access the secret bunker but i can't do that because i don't have the chip anymore, am i screwed or is there a way to get the chip back
The only way is to go to a previous save file before you gave him the chip. Otherwise whats done is done. Most decisions are final. But thats the best part, you can play the game through several times and chose different paths.
This is correct!
