I had alot of trouble finding the right gun for me,
M1 Garand and Thompson have worked well,
but i think my fav would have to be STG 44
my favourite area is the base.
But man, I hate the bazooka n00bs. All they do is run around and shoot at the ground. If you encounter one, sure, you can make it so that he kills himself, too. But when you do that, it's hard to establish rolls and get your score up.
@Wii-Fi: Tell me about it. Sometimes it's one headshot, othertimes it's a full clip into his chest and he still doesn't die.
