Ordered steps
The farming loop
Five steps that turn one run into steady income.
- Step 1
Pick the highest wave band you can clear without dying — that is your income floor.
- Step 2
Maximize kills per run: position defenses so zombies funnel into weapon range, since every kill pays.
- Step 3
Bank cash into damage upgrades that raise clear speed first — speed compounds into income.
- Step 4
Push one wave band higher once clears feel comfortable, then repeat the loop.
- Step 5
Use the cash calculator to sanity-check your estimated earnings against upgrade prices.
If you're stuck
Farming fixes
- Income stalled: your clear speed is too low — drop one wave band and farm faster.
- Dying before payouts: add survivability; a failed run earns less than a safe one.
- Cash per run varies wildly: your kill coverage is inconsistent — tighten your kill zone layout.
- Not sure what to buy next: follow the tier list rankings, then the best build page order.
