The Abyssus is a simple mouse, perhaps best demonstrated by its driver control panel:
The past is strong in this one.

Yep, that's it. This looks mighty similar to the driver that came with the original DeathAdder over five years ago, but don't let the layout deceive you — there's still separate X/Y sensitivity, and you can still assign custom functions to the different buttons; just what functions you can do are quite limited.
For instance, there are macros included, but you're limited to 16 strokes, including down and up key presses, and are remembered per button, rather than across multiple profiles.
