San Andreas, here I come.
On a slightly related note, scientists in Philidelphia have created zombie dogs. By draining the victim's blood and replacing it with a near-frozen saline solution, the scientists were able to leave the dogs legally and scientifically dead for several hours before reversing the process and using an electric shock to get the dog's heart working again. The zombie dogs appear to be in great shape, without any health problems at all. This process would supposedly be used on humans in circumstances where the victim has lost a lot of blood, such as in car accidents or stab victims. Finally, I can actually relive my Grand Theft Auto fantasies and actually respawn! Score!
