somehow I could see a promotional event could be held with a filming crew / headcams / cameras where two teams of hired expert parkour'ers can 'dress up' as the characters and go nuts at each other in a themed venue, not sure how good a promotional idea this is, but i sure wanna see it.

Promotion idea for Splash: give me a free copy. Excellent promotion that thar is.

That reminds me i gotta got the valve in my M16 fixed...

If this is happenin' be sure to let ME know! Cuz ur idea sounds awesome and I parkour. If you need an asian looking intermediate traceur. I'd like to dress up as one of the characters, especially the Anger.

It seems to me that you need a following for your game before you license things like airsoft and paintball guns, rather than the other way around.
