[Zombie]

Some adjustments to the Zombie waves and values. Mini-Bosses like Sludger, Havoc & Buffalo are treated as Elite versions of their weaker Bloat, Gunner & Dog. Therefore they are no longer severely overpowered. We might add a real Boss Zombie in future, that spawn alone in a boss wave, supported by weaker Zombie types (Infected, crow, dog).
