It's just you, grenades are great tools for uprooting campers.
Yeah, I know that they are, after playing for a while longer I've figured out that the problem is not camping but a lack of teamwork on the team based games, everybody is trying to get their Aces maxed and they don't really work together to remove the campers that are causing the problems, in the original Vegas, this wasn't as big of a problem because there was nothing but XP for unlocking new weapons. Also, you know you are on a camping game when you get in and grenades an C4 are restricted. It's still a good game, I'm just a little disappointed.
