Defiance quite a bit. The latest developer diary for the game might be answering questions you hadn't asked, however, as it's focused on explaining how the game blends the MMO and shooter genres together into a cohesive whole. But there are still interesting tidbits about the game, including a look at vehicles and character advancement.
Characters advance partly through the acquisition of powerful new weapons, which is almost a given based on the nature of the game. Weapons are also heavily customizable, with visible differences between stock weapons and customized versions. Players will also be able to acquire points to spend on special abilities of varying types, although points can be swapped into different abilities later on.
