Check Out My Dogs
When you first played the prologue and finished the tutorial you will be able to pick a campaign, when you back out of that menu you will see another menu what says *play game*. Pick that one and choose Dog Tags, here you can change your dog tag.
For those who has played Resident Evil 5 there will be a title award for it, although you have to finish RE 5.If you select this one the achievement will pop for you aswell, otherwise you have to play a little bit to unlock things.
Some people in the comments tell that you don't have to finish RE5 to get the Curious Fan Title, just have a save on your hard drive.
