what do the 0, 50%, and 100% settings do?

when i start arcade mode, i get to choose a map. Below that, I can choose 0, 50, and 100% settings. What do they change?

Also, can I change the game's settings so that all the weapons are more lethal? I like the idea of being blown up with one or two bazooka shots :)
