I've found that "surrender rules" suck in almost all circumstances. It's simply too much thought and too much "weighing the options" to be processed by a renter. Paintball is played at warp speed for someone who is inexperienced.
Even in places that have these rules I tend to stick to the bang method: Come screaming around the bunker, gun up, shouting "bang bang bang" at the back of their head. Keep going.
They know they've been shown mercy.
I've never been turned on like this. If someone ever did you'd be sure I'd call myself out...
and then shoot that player right in the center of the butt the next time around.
...'cause bandaid's stuck on me!
