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 | 47,211 | Tier 5 |
| Standarddefault | 62,944 | Tier 6 |
| Strong | 78,661 | Tier 6 |
| Very Strong | 94,373 | 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.
