Is this your first time playing the Counter-Strike Series? Decided to start with CS:GO?
Here is an encyclopedia of certain terms that you will hear in the future in the game.

Pub, public-a place where a noob with a Skin for Five thousand in respect, unlike Pro players with Stock guns
MM-a Place where you will throw out all the water in the form of sweat until you turn blue until the twentieth. After that, the game goes into the "♥♥♥♥ it all" style..."
Poles are Famous inhabitants of MM, beings who are dissatisfied with ABSOLUTELY everything that you would not do. Anything. Even if you dragged with 1 HP against five with only one gun. The main thing is not a word in Russian.
Russian-Famous inhabitants of MM and public places, obscenities clog the chat. If you suddenly need information from your Russian ally from random, you will hear something like "Somewhere there ran", "here it seems was" and "it Seems here". After turning 180 degrees and checking some positions, the enemy was behind.
The case Is made of Gabin. You stick in 120 rubles ($1.5) and take out literally pennies.
Skins-Coloring weapons that determine the skill of the player.
Avapa, Avape, AVIPI - If you think that the best training is in combat, then put this phrase out of your head and never run with this sniper rifle, which judging by the movement in the sight weighs 50 Kilos, if not more.
Emka is a Weapon that Counter-Terrorists always prefer to take As a trophy
Kalash-Weapons from Terrorists, which Counter-Terrorists always prefer to take as a trophy

Overall impression of the game\The comparison with the Previous Series, I like about 60-70% Community Contra I play it with 1.6. How does it differ from GO?
- Shooting is more random than in 1.6. You will think that on the sky of any map there is a magnet that attracts bullets. In fact, this is not the case. I checked. Strange, isn't it?
- Grenade physics. Despite the fact that real grenades weigh about a kilo-half, here they fly off like feces on The toilet tiles. Be careful with alternative fire when choosing grenades.
- Physics in General terms. If you suddenly see a terrorist twisted after death as if he does not have a spine at all - do not be surprised. The modified engine allows you to capture the best moments of breakdancing corpses. Don't you believe it? Community GO-Screenshots.
-Graphics. If you think that your girl asks a lot of you (If you have one at all, and you know what a female person is), then you are mistaken. This game will eat up absolutely all your RAM and will give out a puny 100 fps if you have less than two gigs of RAM. Slide show when shooting is provided.
-Weapon. There is a new one. We will have to talk a lot about it. Buy it and see for yourself.

After such a long time of writing a useless assessment, which will only be looked at by two or three people at most, I want to conclude my review with a General conclusion.
The game is very good. If you get used to it after hours so 100, then you will understand what its trick is. But the game is unfortunately merciless to beginners. If you really don't want to get caught by players who think the muzzle of your gun is edible and bite it when you take rush plant together, then you should train your reaction, shooting, throwing, and tactics in General. And remember-never lose heart. This game will eat your nerves as well as mine. The main thing is not to lose heart. One day you will become the same as professional players. The main thing is patience.
