You are the once-trusted bodyguard of the Empress. Framed for her murder and driven by revenge, you must become an infamous assassin, known only by the disturbing mask that has become your calling card. As you navigate a world torn apart by plague and oppressed by a government armed with strange new technologies, the truth behind your betrayal is as murky as the waters surrounding the city. The choices you make will determine the fate of the world, but no matter what happens your old life is gone forever.
Nice story, memorable moments, good level design, underrated Visuals, fun to use abilities and a good length, steam said 25 hours, but that's with the DLC included with GOTY edition. The downsides of this game is slightly frustrating combat and partial mana regeneration which ruins some role-play game mechanics.
If you find this on a sale this may be very priceworth.
This game feels something like Deus Ex but steam-punk themed and newer.
