Thanks for posting this game up, it is great! I don't have the link in front of me, but there is an thread in their forums that describes the mechanics of hiding. It has some decent info on how to set up or pick good spots. Like hiding behind bushes, 1 bush is good obviously, 2 are better. Behind 2 bushes makes you 100% invisible,but you have to be with in 15 yds of both. Also the hiding is at it's best when you are BEHIND the bush, sitting inside of a bush gives you some cover, but not near what being out side of it does.
I haven't shot any team mates YET but I had a team mate blast me at the start the other day. Right at the start the tard just opened up on the whole team and nailed my rear. Killed me ,and damaged several others. I was PISSED.
