I've been thinking about whether or not I should have a COD4 shotgun class like this:
Primary: (Shotgun) w/ Red Dot Sight Secondary: USP .45 w/ Suppressor (Who loves this pistol? I do.)
Perk 1: Bandolier Perk 2: UAV Jammer Perk 3: Extreme Conditioning
The only other two useful Tier 2 perks I can think of to use with shotguns are in an Overkill class or Sleight of Hand. Juggernaut is also possible, if I really want to piss people off. (Sorry I'm getting off track here) This class I'm using primarily to get headshots for shotguns, because normally, it's a pain in the ass to get shotgun headshots. With this class, I can theoretically sneak up on some poor camping or sniping sap, aim for the head, and fire away. However, since shotguns in COD4 can't accept suppressors, I'll be giving my position away when I fire, which kinda negates the stealth part. So is this a good idea or not? I don't think I have enough COD experience to judge this for myself.
Oh, and what is World at War's multiplayer like compared to COD4 weaponwise, as I'm thinking about installing WaW. (Man I wish I didn't have to pay for the other 3 Nazi Zombie maps. But Treyarch has to make some bucks I suppose...)
