The whole disguise thing was awesome. There were so many new an innovative things about that game... it was a rough diamond.
As for "he's packing", it was what an azn civilian would say if they saw you had a weapon. Unfortunately, every civilian screamed that same thing, which made it annoying. What was more unfortunate was the fact that some of them had x-ray vision -- it is the only explanation -- and they were nosy as HELL. Why did they care what I was doing in my corner, god knows.
