The effect of Rapid Fire attachment on Single Fire Weapons

I don't pick up a second weapon beacuse its better then my first. I grab weapons so I can build an arsenal to deal with any situation.

For instance, if I'm doing a sniper mission the first thing I will do is replace my sidearm with the first shotgun, smg, or assult rifle I found. Carrying multiple guns gives you the versatility to always have the appropriate gun for the appropriate situation.

Finally, don't forget that its faster to switch weapons then it is to reload. Carrying a second gun you enjoy can make your charge 2x more awesome!

Hope this helps

No one can really tell you. All of the guns are suppose to be "equal" but in their own way. You wouldn't want to use a sniper rifle for close range(quickscoping isn't that easy!), nor would you want to use a submachine gun for long range.

How do you commonly play?

Personally, I like to run and gun. I stay still very little and prefer close range combat. As such, I usually use the submachine guns and assault rifles.

If you prefer to stay back and pick people off from range, you'd probably want snipers and assault rifles (maybe with an ACOG).

If your accuracy is sub-par, you may want to spray and pray by using a large machine gun with a 200 bullet clip.

The main thing is, just try out all sorts of different guns and perks. No one can know what class is good for you except for you.
