Awesome Ramm
If you're interested, a variation of gun game I really liked was making it so you start with the strongest weapons, like a LAW, and slowly work your way down to the weapons that are hardest to get a kill with, e.g. the machete. Once someone gets a kill with that final weapon then the game is over and they win. (obviously a multi kill only would only pass them onto the next weapon, not put them 2 or 3 weapons down the line)
That way at the end of the game players are frantically trying to get their last kill to win, while getting shot at by the players that haven't yet got that far. It means that if 1 player is really good and the rest are not so good, then the top guy isn't always ahead of the rest of the group getting easy frags
