Call of Duty and HALO

So there is just under a month until the next Call of Duty game is released.
The Call of Duty series have been one of the most widely bought first person shooters for most of my friends, although those that love HALO don't really care for it they will still play it. The only down side of flipping from HALO to C.O.D.(call of duty) is the controls. They very by allot, but it is fun if you have someone who hasn't played a first person shooter before, and you have them play HALO for about twenty minuets then switch to C.O.D. The thing I like best about C.O.D. is that you don’t have power ups or shields like you do in HALO, it's more like life. With the exceptions of some factors, for example in real life a 9mm pistol has a max effective rang of about 50 meters, but in the game you can get a kill from across the map which can be a few hundred meters. Also in the game some of the weapons are misrepresented, in the game they have the 240B. A belt fed fully automatic machine gun, in the game when you fire the weapon the carrying handle bounces like a kid with fire ants in his pants. If that were to really happen you would immediately stop firing and replace the barrel because the handle should never do that.
All in all though they did a very good job at getting military accuracy. Most of the weapons and equipment are close to the real thing and some of the lingo in the game matches up with the real thing.
