Buying this game soon, any tips?
Yes:
1. Don't smurf, noone likes them
2. Good luck with becoming ranked if you have never played before
3. Don't treat the skins as a job, meaning dont go around hoarding skins
4. Please for the love of God make sure you have a mic, you will most likely lose if you or your team doesn't have a mic; and yes there is teamchat and global chat ("U" is default team chat and "Y" is global chat, "K" is default push to talk button)
5. Play Dust II as a starting map
6. Have fun, and again, if you end up in silver don't listen to the people that make fun of you because you are in silver, you are doing the best you can and silvers are not all that bad.
7. Don't get mad at your team, it makes the chemistry between your team bad and you will most likely do bad
8. Don't open cases if you feel unlucky, buy the skins yourself and possibly save some money
9. Don't pull what i did and complain about CSGO in the forum topic
10. Some common abbreviations: GLHF (Good Luck Have Fun, often said at the beginning of the game when the countdown is ending and you cant move, some people like to say Good luck have fries or Good Luck Have lunch or combine them to say Good Lunch Have Fries) GH (Good Half, often said at half time if your team and the other team isn't salty) GG (Good Game) and VAC (Valve Anti Cheat, often used when you see someone obviously hacking, just make sure it isn't a smurf first, they like to ruin the experience for new players)
11. Just have fun, many times, you are actually on the smurfs team and they will carry you, but other times there aren't any smurfs and its fun. So GLHF dude!
Also, there are other fun servers like jailbreak and Zombie escape, those are pretty fun oh and minigame servers as well as Surfing servers.
