Basically zombies like edgar. Upgraded version of the orginal.

Tank: More HP, Can climb, more punch dmg.

Crawler: More speed, More attack

Hunter: Faster energy regen/Decreased energy usage of the jump.

Elemental: Uses both attacks at the same time (Freezing fire and Fire drop.)

Boomer: More speed, more radius, more dmg.

Cavebat: (Name is batman) Can run, scratch dmg of a smoker, speed of a crawler, flight, and acid spit. (Totally not OP at all)

Duck: More radius and dmg.

Because smokers aren't that special to have an upgraded form to themselves.
