Its not to bad. Its a change, worlds very grim dark, and your not exactly hero. Not fully villian, but im sure aztek would feel but quizy with some of the SLAs methods. But even then lots of the terrible stuff is frowned upon by even their own.
Its interesting, and weird. Havent heard much else from other people aside from a deep dive into the secret background from original writer which is a weird twist.
End result is a splatterpunk/horror game where your the nominal good guy. How the game shapes is gonna depend alot on your gm and players.
For our group its turning very tongue in cheek and like, old early 90s anime ovas of the angel cop and others style. Stylized trash on purpose.
