cars:
scope...maps are too small, people move too fast and vehicles would slow peoples computers. this idea is absolutley useless for this game.
Big gun:
why do we need 1 big gun when autocockers are better than anything you can make and you can carry it around.
Grenade launcher:
that would be fun getting killed by grenades every round. again maps are too small in this game for some thing that powerful.
scope your ideas however good you may think they are, arnt right for this game and they are not original. people have been requesting these ideas for years and they just dont work.
