Most of the game can be done on stealth but it's EXTRA difficult on many missions, and sometimes they end with a big explosion that last second erases your disguise, but still pretty much doable!
😅had no idea Sean is that strong so i myself placed a dynamite (or maybe even an rdx) and upon blowing i just waited for the sus zone to die down,then i did the rest just like you did
This uniform is from the mission where you chase Dierker in a Zepellin. If you don't rise the alarm you get to keep it after the mission. I recorded this gameplay just after finishing the previous mission. It can only be obtained via THAT specific mission or with mods.
