There is no best class in MW2 it all depends on your play style but if you just wanna go easy try out the M4A1 with a red dot sight slieght of hand, stopping power, steady aim, semtex a stun (animation goes faster than a flash or smoke) and a PP2000 with FMJ...
the heavy class
for me assault is the best class
The AK-47 should be your first pick.
You may create your own class in call of duty, by entering the main menu of Call of Duty 4 Multiplayer. Then you click the title showing 'create a class'.
The best at Call of Duty is who invented it.
You cannot customize classes until you reach a low level (around 3-5, i believe). Then you select the Custom Class 1, and go to the bottom of the options (Primary, Secondary, grenades, equipment, perks) It should be an option towards the bottom. Rename Class.
In my opinion, the best class for call of duty world at war is this:MP40 with dual magazines367 MagnumFrag grenadeTabun gasBandolierStopping PowerDeeper bullet penetrationI got a 30 kill streak on free for all with this custom class and I could have got higher if the game didn't end there.
Call of Duty Is the best game in the world. because in World at war of can beat the game in get Nazi Zombies.
call of duty modern warfare 2
The best class I have is a chicom with the EOtech sight and a ballista with variable zoom 1 shock charge and a betty with ghost and toughness with engineer.
the most new game in Call of Duty it is most exiting but the sniper shooting is the the best of all of call of duty.
The best one would have to be Call of Duty 3 on PlayStation 2. Yes you can go online on it.
