[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). - More balanced waves - Reduced overall Crows - More standard Infected overall - Less Napaln, Slasher, Punji & Bomber - Introduced Sludger, Havoc & Buffalo in earlier waves - Adjusted several zombie types Slasher - Reduced attack damage from 15 to 7 Bloat - Reduced attack damage from 25 to 15 - Reduced fart cloud lifetime from 20 to 15 Napalm - Reduced attack damage from 15 to 9 - Reduced fire lifetime from 3 to 2 Bomber - Reduced health from 350 to 250 - Reduced attack damage from 35 to 7 Ranged - Reduced attach damage from 35 to 20 Screamer - Reduced attack damage from 23 to 20 Gunner - Reduced attack damage from 35 to 25 Havoc - Reduced health from 2000 to 1000 - Reduced attack damage from 50 to 35 Orange - Reduced health from 1500 to 1250 - Reduced attack damage from 65 to 30 Buffalo Reduced health from 3000 to 2000
