Neon Zombies (Basic Trio & Flag):
 * Pretty much re-skins of regular zombies
 * May have a slight difference since it doesn't use the same class as all other Basics.
 * For example, Cowboy Zombie uses a different class compared to other Basic Zombies because it has a hat that is considered armor by the game.

The JamStyle stuff is tied to the MusicalJams mechanic present in NMT levels. In addition to triggering special abilities in certain zombies, it appears to have a slowdown or speed up effects on zombies:
