Pros:
+ Quality FPS
+ Free
+ More realistic than other FPS (HP wise)
+ Need to be skilled (it's not Warzone (COD)
+ Large community & tournaments
+ New maps and updates
+ Operations every once a while (assuming yearly)
+ Making friends that stick with you for life

Cons:
- cheaters are common thing
- full of kids (but not suitable for kids "Toxic")
- Playing solo is not a good idea always
- Buy prime or level to 21 for prime (less cheaters, but they will exist!)
- Low trust factory if you unlucky and got with a cheater
- Could also result in 7 days cool-down from the game

General:
Recommendation, I will give it a 7.5/10. Play with friends, PRACTICE SOLO ON WORKSHOP MAPS!!! It is the best way of improving aim placement, which results in better head shots, one taps, and higher chance of good peek. Communicate with teammates... it is obviously the game is intense, it needs communication to have a higher chance of winning. DON'T BE A ♥♥♥♥ ABOUT RANK (Win/Lost). If you lose, then you lose, don't rage or mad at teammates. Watch propositional players on YouTube, to learn how they peek to clear either A or B cite. The more you watch, the more you learn. Watch = New Skills. Enjoy the game!
