The Xen games in general are well-described, with extensive backstory and compelling characters.
In this sequel, the powers you discovered in part 1 are out of control, and the police (and others) are hot on your trail.
The game includes chase sequences, extensive conversations, cutscenes, etc.
Unfortunately, the author didn't find a good way for people to discover this stuff on their own. It switches between extreme railroading and extreme lack of guidance. But I enjoyed it.
