The official website of Huxley released race and class information. The details are as below:

Races and Classes 

There has been little updates lately about race and class information.  This is a collection of a older video and small sniplets of information combined to get the most accurate information possible.  But expect many things to change, once we devolopment moves forward.


Classes : There are three classes in Huxley,  listed below
 
Enforcer: Heavy assualt class, moves slower, heavy armor,  can most likely carry and use larger weapons.
Avenger: Medium assualt class, moves fairly quick, medium armor,  a good overall balanced class. 
Phantom:  Light assualt class, moves very quick, light armor, primarly a sniper class; but could be more stealthy fighting also.

Races : Two main races, each have two sub-races
 
ALTERNATIVE: ALTERAVER

The impression from their big body, tough face, strong and brave mind of Alteraver gave them the image of an warrior. They are simple, devoted to their society, warm-hearted and kind. But Alteraver never forgive enemies who threat existence of themselves and their precious things. They trust others easily because they are naive and have little intelligence, so they often tend to be imbued with bad ideology. Alteraveruse high-powered weapons empowered by their physical strength and power. A troop of Alteraver has enough power to make their enemy demoralized.

They used to fight on the frontline of battle at independence war. While they under the oppression of One, they learned by force to operate heavy equipment. Those skills helped Alteraver to build their country after the independence.
