there are some pretty good blood and bleeding effecs out there. I think the one that came with the game was pretty good, is there any (that i may not know of) that are runny, like the one that came with the game. Not just the same running pattern each time, but is it possible to make some real unique bleeding patterns, so the blood bleeds out a few feet, maybe even how far depends on where the guy gets shot, i think this might be impossible, but you never know with this game.
