Cash is obtained by the Heroes in a number of ways:
- Common zombies such as Walkers drop from 10–1000 dollars.
- Special Zombies like Thugs and Rams drop 100–3000 dollars.
- Cash Registers may hold 5–5000 dollars.
- Wallets (also found in luggage) may hold 8–300 dollars.
- Completing certain quests will bring the Heroes a substantial amount of money.
It should be noted that the higher the Hero's level, the more money they will receive. For example, a level 16 character receives about 1200 dollars less from cash quests than a level 28 character.
Once you reach the Laboratory there are 2 safes on the premises of the main building that regularly contain 2-4k in cash. There are also cash registers located in the Supermarket district in 2 shops located just Northwest of the Warehouse safe house. By fast-traveling between looting the safes at the Lab and the cash registers in the Supermarket district you can easily farm lots of cash in a short time frame.
