How to Get Cash Fast in Build and Kill Zombies

How Cash is paid

Every run pays Cash for distance, shown in green under the distance counter while you drive. In both videos we checked, that number is exactly 0.4 Cash per stud, rounded down:

Zombies you hit pay on top of that; a counter climbs above the car as you plough through them. The 2x Cash game pass says it doubles both: “Works both cash earned by killing zombies and distance travelling.”

Four ways to earn faster

1. Go further. Distance is the base of every payout, and runs end when the fuel gauge hits 0%. A bigger tank is the single upgrade that moved distance most in the footage (1,363 to 2,289 studs). See the parts page for the fuel pads seen so far.
2. Hit more zombies. A second weapon slot (More Support I on the skill tree) lets you mount two weapons. Face them forward so they meet zombies first.
3. Redeem the codes. The five codes are worth 1,500 Cash plus an engine, a tank and two seats you would otherwise roll and buy.
4. Spend less on rolls you do not need. Rolling was free in the videos; only buying costs. Skip parts you will not mount.

Robux options

The shop sells the 2x Cash pass (179 Robux) and five cash packs. The Mega Pack is the best value at about 139 Cash per Robux (250,000 for 1,799); the Tiny Pack is 40 per Robux. For scale, the Tiny Pack’s 1,000 Cash is about one 2,500-stud run.

What to spend Cash on first

• Luck I (75) and Luck III (625) make every later roll better.
• Unlock Gold Roll (500) opens its branch once the tutorial is done.
• A fuel upgrade before more weapons, because a longer run pays more for everything.

Keep an eye on the Hacker Event too: its shop takes Hacker Tokens, not Cash, so tokens from the HACKER and 1x1x1x1 codes do not compete with your Cash. Details are on the Hacker Event page.
