Having trouble getting Zombrex for your dear daughter? Fear no longer! Certain missions give out Zombrex for rescuing survivors and you can even find some sitting around on high ledges.

1 // Code Blue, Inside the Slot Ranch Casino: Behind the stage curtains there are some equipment boxes. Jump on them, then to the giant dice, and finally across the gap to claim your prize. You can easily see the Zombrex beforehand, but not jump to it, if you walk up the metal stairs.

2 // Code Blue, Inside the Yucatan Casino: Go to the giant idol in the center and simply jump up the conveniently stair-shaped sides until you reach the offering plate. There you'll find some Zombrex and a Light Machine Gun.

3 // If you are finding it hard to come across some zombrex rather than buying it, why not find it? If you check out the stage in Slot Ranch Casino head behind the curtain and to your right side is some boxes. Carry on around towards the maintenance room behind the stage and climb the boxes to the right of the door as you face it. You will see a nice free bit of Zombrex on top of the highest boxes. (Note: You cannot jump to the boxes from the overhead mez floor).

4 // You can find some extra Zombrex in the underground tunnel after completing the "Ticket to Ride" mission. It is near the underground access ladder underneath the Atlantica casino.

5 // In Big Roy's Mart in Royal Flush Plaza (case related).

6 // Go to the stairs in Bennie Jack's BBQ Shack in the Americana Casino and turn right when going up the stairs to the second floor. Jump on the balcony and then onto the closest light. Keep jumping across the lights until you reach the end.

7 // Backstage behind the curtain at Slot Ranch Casino. Climb up a stack of boxes and speakers. Jump onto a smaller stack of boxes and speakers to find it.

8 // Save the paramedic in the "Code Blue" mission. Bring the paramedic to Dean ("Once Bitten" mission), and the paramedic will give Dean a free Zombrex.

9 // On top of the tallest slot machine display in the middle of Yucatan Casino.

10 // Defeat the Postal Worker (mission related) in Royal Flush Plaza.

11 // Bring Richard (Hunger Pains) food and rescue him in the Silver Strip Diner.
