actually you just need to hit the update server button. but steam will give you problems sometimes. you may need to load patch 1.3, 1.4, 1.5 and steam will load 1.6.
My suggestion is:
For close to mid range, use the mp-5.
For long range use the m4a1.
I would suggest sticking to those two for untill you learn how to play. beware, use the auto-shotty or big a$$ machine gun and you **** off every one. Also, start each round with armor and and a helm.
You should also have someone send you a buy script, (1-button auto-buy). it'll make it much easier. you can write your ow but its easier to just re-write an exsisting one to fit your play style.
If your running low on ammo with a guy near, DO NOT RELOAD. switch to a pistol or knife (and get used to that cause you'll use it every round. Dont reload till you know its safe or its a must.
This is where the pistol picking comes into play. I suggest the D.eagle or dualies. dessert eagle of course is very strong, while the dualies gives no recoil and fires fast. (using dualies, if you dont aim near the head, dont even try using them, they'e too weak to rely on shooting threw armor.
Arrange your mic key handy, using it to cummincate with team makes killing your enemy much easier.
Dont try to use a sniper rifle yet, you'll just be an easy target.
Also, this is a first person shooter, so turn your bass way up. if you can hear then comming, your that much better off when your actually facing them when they come up behind you.
Hope this helps, and good luck.
