Ever watched the scene in the gameplay trailer where the character performs the finishing stab in the chest with his sword by the water and think it would be cool if that guy fell in the water and his blood made the water turn red as he floats downstream??? I think that would be cool tell me what you think?

Yeah, lots of games had cheesy pools of blood before, hopefully they'll be more realistic.

I think it's a difficult thing to put in realistically because blood will act differently based on terrain and texture of said terrain. It can be absorbed by soil or snow, or flow away in small streams between the rocks if the victim falls on a cobblestone road, or, if you say, fall into the water and turn it red flowing away with the current. I think it would require a lot of time to code it in such a way it behave realistically, no matter the circumstances. I'm not sure if it's even possible.

But yeah, it would be awesome.
