When the zombie outbreak reached uncontrollable levels on September 24, 1998, Bob was already on the verge of complete infection, feeling the same intense hunger the already succumbed victims felt. When a zombie entered Jack's Bar, the unsuspecting bartender, Will, was attacked; Bob fell unconscious as the zombie arrived, preventing Mark from helping Will. Though infected, Bob has no visible injuries and appears oblivious to any strange events that may have caused such, suggesting that he was one of the many citizens of Raccoon City infected through tainted drinking water.
The player has the option of helping Bob up to the roof of the bar. When reaching the roof, he attempts to commit suicide. Whether he succeeds or turns into a zombie before he can shoot depends on the difficulty level.
As an AIPC
Bob can get damaged by zombies during the Outbreak scenario, however he can't be cured by Cindy Lennox, nor with the help of First Aid Sprays. If zombies manage to kill him before reaching the rooftop, the player won't be able to obtain his handgun. He becomes a liability in play due to the fact that his starting condition is Danger and he's already infected with the t-Virus. On higher difficulties, it is not uncommon for Bob to be killed before the player even reaches him. If you do not play as Mark and select Lone Wolf Mode there will be no Bob.
