Day 1: Hunt for Zombrex

Katey will need Zombrex every 24 hours to prevent turning undead. You can gain Zombrex by completing certain messages, finding them through platforming, or even buy them from pawn shops.

Stacey will inform you that there is some Zombrex in the Roy's Mart on the east side of Royal Flush Plaza. Exit the safe house and you'll be on the north west side of the Plaza. Grab a few melee weapons, such as the sledge hammer and bat along the way.

Upon entering Roy's Mart, you'll be attacked by a group of three looters. Each can be killed with one or two swings of your hammer. Be sure to take out one at a time, as it can be risky having them gang up on you. If you require healing, there is some orange juice on the east side of the room, which will restore three life bars each.

After the battle, rescue the pharmacist, Denyce, who was behind the counter. You'll gain a key that will unlock an employee lounge, where a box of Zombrex sits. Return to the safe house with Denyce and administer the drug to Katey at 7:00 AM. Afterwards, Sullivan will give you a maintenance room key, which will allow you to make Combo Weapons. You'll learn the first weapon, Spiked Bat, upon entering the room. It is a simple weapon made from a box of nails and a baseball bat.
