Contributed By: FishOfPain. 2 1. For Grand Theft Auto IV on the PC, a GameFAQs Q&A question titled "Serial Number???".
I thought my manual was in my case, but it wasn't, so now I don't have my serial number anymore. Is there any way to recover it? Like through Rockstar Social Club (or w/e its called), or can Ihow do we find the serial code? when i launch the game it says serial and then below it it says unlock request code but i dont have a serial code where would i find it?
