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 | 38,307 | Tier 5 |
| Standarddefault | 51,073 | Tier 6 |
| Strong | 63,827 | Tier 6 |
| Very Strong | 76,576 | Tier 6 |
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.
