Ten Ton Hammer has posted nice little reivew of Fury: 

A hybrid first person shooter / massively multiplayer online game is difficult to wrap your head around at first, but the most basic premise of Fury is this, you fight other living breathing, or in my case gasping, wheezing human beings to gain levels. As you advance in level you gain access to new spells and skills which you can then put into play against even more living, breathing human opponents.
