Huh, I play that game occasionally with my friends that are too cheap to buy TF2 and L4D. They actually update it more then a lot of shooters, seeing as only what, last February, was it? they created a new Snowball fight mode, and just before in like December was another mode before that. Although you guys have to remember, this game is from the same studio that made Maple Story, so odd stuff like this is assured. Well, guess what me and my friends will be playing all week!
Oh, and the reason the groin shot would only affect male character's in that game is because you have to purchase the female character models with the in-game cash you get for winning battles.
