Before the zombie outbreak in Fortune City, Luz was a professional golf player.
During the outbreak, Luz is found in SporTrance in Royal Flush Plaza, fighting off a crowd of zombies with a golf club. After the zombies are defeated, Luz thanks Chuck Greene for his help and agrees to follow him to the Safe House. She refuses to give up her golf club, and cannot be armed with another weapon or given food.
Later, Luz tells Chuck that her favorite golf club has gone missing, and requests him to get her a new club. She offers a tidy sum of money to pay for the favor.
Depending on the ending, Luz was either rescued by a helicopter sent by the Channel 6 News Station, killed by the military firebombing, or killed by the military rescue squad to cover up the truth behind the outbreak.
Her last name, weapon choice, and profession may be a reference to Arnold Palmer, a famous American golfer.
When she uses her golf club, she will hit zombies with it, but if Chuck uses it, he will hit zombies with a golf ball instead of the club.
Luz is one of three survivors with particularly large total PP awards associated with her (the others are Randolph and Jared). In addition to her joining and escort bonuses (15,000 and 30,000 PP respectively), successfully completing "Bent Wood" will give the player a whopping 60,000-PP fulfullment bonus. All three of these awards are affected by the Rescue magazine, and the first two bonuses will be further boosted if Chuck has Playboy along as well. Therefore, helping Luz could award Chuck as much as 135,750 PP.
For an unknown reason, other than the large amount of zombies that suround her, Luz has twice as much health as a normal survivor, an attribute she shares with Denyce Calloway and Tomomi Miyamoto.
