GTA 5 will allow you to create 'hereditary' avatars using GTA 4 and GTA 3 characters

GTA 5 will allow players to create their on avatars as if they were children of previous character from GTA 4 and GTA 3.
That’s not the type of sentence you hear everyday, we know. Basically, you choose two ‘parents’ – which can be previous GTA characters Niko Bellic, Claude and Misty – adjust some settings like who has the dominant genes, and you end up with what the offspring would look like.
This will only be available to those who buy the collectors edition of GTA 5, as will a host of other bonuses and special options.
