Ive been walking around for hours and cant find this guy. I have everything done but the treasures and this tax evasion trophy. I dont want to start MP until I get all the story mode stuff done. I might just have to give up.
I noticed him a few times during the game, not realizing that there was an achievement for killing him. I didn't even know he was a tax collector. I thought he was a thief or a courier. Once he surprised me by popping up literally inches from my face while I was running along the rooftops. Instinctively , I assassinated him with my hidden blade and the achievement unlocked to my surprise/delight. My only advice is to stick mainly on the rooftops. It's a lot easier to spot him up there than on the crowded streets.
Thank you Dreamer. Ive been hangin around markets and such figurin he would show up but I still havent seen him. My son started his own game and finished it and he never saw the tax collector once. Crazy
