Incredibly fun. Doesn't really feel like a game from 2012. Very easy to lose yourself just skulking around rooftops and window ledges in the open areas and forget you have a main mission objective. I regret that I didn't give this a try sooner but glad to play it even in 2023. I received it for free as a gift but even if I didn't it's easily a $60 game. I could see myself a decade ago grabbing this at full price or close and losing upwards of 100 hours just going through all the different ways to do a single mission, high chaos vs low chaos, side quests, and just running around as a mischief of bloodthirsty plague rats eating every bit of flesh in my path.
