What beating it pays
A wave's total HP sets its reward tier. Each tier pays its reward, and the zombies you kill leave loot on the ground.
| Zombie Horde Intensity | Total HP | Reward |
|---|---|---|
| Weak | 7,531 | Tier 3 |
| Standarddefault | 10,025 | Tier 3 |
| Strong | 12,535 | Tier 4 |
| Very Strong | 15,033 | Tier 4 |
The game also adjusts each wave to how ready your home is (doors, defenses, supplies and how the last wave went), so the HP here is the starting point.
