I know how You react on this subject Luthier, but please close Your eyes, count to 10 and tell us something more about tracers (it's my fetish

). We've already seen one type, yellow smokeless ones. What other types do we have in the game, how they look, do they ricochete? Which one generate smoke trails and are there any conditions (weather, altitude) which makes smoke to appear?
I would be extremely happy to see before a release a short video presentation (2-3mins) covering only tracers.
