To an extent I haven't seen in other scripts, Kill With Style's effect on gameplay varies with the level you play it on. In some cases, you'll more or less play as you always do. In the more fun instances, you'll end up chasing each other up and down the same staircase, going in circles until one of you can line up a good shot. It's a hell of a lot of fun.
Lua gametype where the faster you're moving when killing someone, the more points you are awarded.
For example, if you kill someone while standing completely still, you get one point. If kill someone while running, you get more points. If you kill someone while running and falling, you get significantly more points. If you launch yourself with a rocket and kill someone while flying through the air, you get even more points.
