In Dead Rising 2: Case Zero, eleven survivors, including Chuck's daughter, along with a single psychopath, have survived the outbreak that has ravaged Still Creek. The survivors have been scattered throughout town and will not come back to the safe house unless their requests have been fulfilled, whether it means getting a drink, Zombrex or a weapon, or reuniting with a loved one or friend.
Dick Jones is the only survivor who does not get escorted to the safe house, but rather to his store to continue his pawnshop business.
Several people survived the initial outbreak. The following is a list of survivors. Those in green are currently alive, and those are in orange are also alive, but classified as psychopaths, individuals who have snapped/have immoral values due to the zombie outbreak.
Former national Motocross champion with a daughter. He and his daughter flee from the Las Vegas outbreak and arrive in Still Creek at a gas station, only to have his truck stolen, along with the Zombrex. He needs to find more in order to save his daughter, as well as a way out of town before the military wipes out the area. He escaped with his daughter just as the military arrived in town.
The daughter of Chuck Greene. She lost her mother in the Las Vegas outbreak and was bitten herself, requiring medicine daily to keep herself from dying and turning. She resides in the gas station after their truck is stolen and her father ventures out to find more Zombrex and an escape route. After narrowly avoiding a psychotic welder, she and her father escape town just as the military arrives.
A soldier who was stationed at the Still Creek quarantine. He was killed when the ambulance he was riding in crashed while trying to get away from zombies and out of town. A radio attached to his body informed Chuck about the military planning on wiping out the town, now that the quarantine failed.
An elderly gentleman found atop of a white van, surrounded by zombies. He was on his way to his pawnshop when the zombies became too overwhelming. He asks to be brought to his pawnshop rather than the safe house at the gas station. Once safe, offers to sell bike parts, Zombrex and weapons to Chuck.
A man armed with an assault rifle on top of the roof of a building next to Still Creek Casino, shooting at zombies. He refuses to leave the rooftop until he is reunited with his missing daughter. He will keep a look out for other survivors, though, until he finally spots his daughter and is reunited and brought to safety.
A balding man with brown hair in a gray suit with a red tie. He was coming from Las Vegas with his wife, Gemini, when he found herself in trouble due to the zombie situation.

After receiving a couple of beers, he will comply and head to the safe house.
A brunette woman in a red dress, gloves and black heels. She was coming from Las Vegas with her husband, Fausto, when she found herself in trouble due to the zombie situation. She had to leave most of her winnings behind, except for what she could carry in a briefcase, and flee to a bar where she is waiting rescue. After being rescued, she is going through personal marriage problems, yearning her gems that her husband gave her, which were left behind at their abandoned car. Once the gems have been returned, she gives away all her Vegas winnings.
A party girl found in the bowling alley with Nikki, who asks Chuck to find their friend Sharon, who was scheduled to marry her brother, Dennis.

An overweight mechanic dressed in dirty overalls and a welder's mask with a tank taped on his back. He encounters Chuck administering Zombrex to Katey and talks about how she would be a perfect addition to his "collection" and how the outbreak has been so much fun, killing zombies and how they're just like killing people, but without the legal hassle, and even boasts about killing the guy next door since he never liked him. He is killed as a car crushes his head in the junkyard.
As an improvement from the first game, the AI of survivors have been greatly improved. The survivors are able to hold up on their own while being escorted to the gas station and do not need constant babysitting. They will even assist Chuck and not injure him in the process.
When a survivor first joins, a tutorial screen appears.
Upon finding a survivor, simply press the button near them to begin the dialogue sequence. In the process of a conversation, Chuck may have to reply multiple times to convince them to follow him. Some missions also require Chuck to carry out certain actions, such as delivering a drink, administer Zombrex or having a particular survivor in his party. Once the survivor is convinced, they will join Chuck's party.
Tapping the button will have Chuck shout out "???" or "???" to any survivors in his party. This command has the effect of causing the survivors to stop their current actions and head towards Chuck. Using this command will cause any existing waypoints to be deactivated.
Tapping the button while holding the trigger will have Chuck shout out "???" or "???" to any survivors in his party. This command will prompt the survivors to head towards the indicated location. Setting a new waypoint will cause the previous one to be deactivated.
The current health level of survivors is indicated on the green name bar. The proportion of the health bar that is green represents remaining health. When survivors have less than full health, Chuck can give them a food item to restore their health.
If a survivor is not near Chuck when enters the gas station, they will be left behind. Their name and health bar will appear on the left side of the screen. The health bar will slowly deplete, eventually killing the survivor if he or she is not saved in time.
