Counter-Strike: Global Offensive has 5 games inside of it. Deathmatch
If you are new you have to play this game. even people with 500+ hours might play this game. In deathmatch you are able to learn how to use the weapons and how to improve your aim. That is why there is a possibility to turn of random weapons to you can choose only 1. PLEASE if you have 100- hours play deathmatch. (Dont use SCAR-20 to mutch.. people will hate you!) Demolition
In this game you have to kill people to get new weapons. Here you will learn how to plant a bomb. and how to use maps. you will learn you have to look back and look everywhere so you wont be killed. Also it is a good way to use multiple weapons. Not like deathmatch 1 weapon youre good with. Arms Race
This game is hard. You need to kill as mutch people as you can. There are 16 levels. every level is a new weapon. kill 2 people to go level up. the first one who is at level 16 gets a knife. If he kills someone with the knife he wins. the maps are small and there are a lot of people. here you learn how to use every weapon (every weapon shoots different) (this will help you in Casual and more important Competitive.) Casual
This looks like Competitive. You have team mates and you have to win. sometimes its 5 vs 5 6 vs 6 8 vs 8 10 vs 10. They maked Casual easier. Them damage is turned of. and you wont get a Cooldown. If you want to play this: in the beginning this will be hard. and you wont get mutch kills. if you play more it will get better.
You choose 1 side and you will stay the whole game that side Competitive
This mode is for players with atleast 300+ hours ( I Thinks.. and a lot of players think that 2). Everybody plays this serious. Cause here you play for ranks. team damage is turned on. Its the same as casual. Kill enemy and plant the bomb. 15 round as Counter-Strike and 15 rounds As terrorist. the team who wins 16 rounds wins the game.
What I also like about this game is the face that everyday over 100000 people are playing. Every mode are people. you meet every day new people and sometimes new friends.
every week you get 3 drops. ( most of the time 2 cases and a ♥♥♥♥♥♥ weapon worth 3 cents. sometimes a weapon with is worth more). if you recieved the 3 drops you have to wait till monday then they will reset it. ( drops are random)
Also there are cases you can open. this is addicted like hell. In a case there are weapons skins. some are worth nothing others are worth 50+ euro.. if you are very lucky 100 euro/dollar or MORE!
EVERY ONE WANTS A KNIFE skin.
weapon skins are useable in game. you can buy them are you can open cases. ( if you dont have mutch money buy the weapons.. not the cases ;) ).
last thing. Operations and championsships.
ever couple months there will be an operation. that means. you have to pay 5 euro/dollar. and you get:
5 New maps. Lots of Missions. New weapon skins. That is cool cause this will make sure the game will stay fun.
Also every couple months there are contest between the best players of csgo. you can watch them live! thats cool!
I give this game a 10 out of 10.
