Maybe not as dynamic as this gas at first, but to add the Necris nightshade velocity effect to a weapon when falling either from a airvehicle befor its destroyed or just jumping off of high areas.
Since there are no temporary force fields for the airvehicles, this would be a good way to save your ass if you decide to make the jump.
The gun isn't that mechanical like most of the weapons for UT3 so alot of detail is a must for firstperson view.
I'm using fraps to take some screenshots of the gun to model to give it that genuine FF feel
