Learn how to play the game
You can rank up very easily in this game and get good stats even without high end gear etc.
I've tried but got around 20 hours spent on it now and find it very boring, extremely repetitive. Go there, take cover, shoot, take cover somewhere else, shoot, collect crap loot. I think Ive deffo bought the wrong game for me personally though as its obviously getting a lot of love from most folks.
Shame really as it looks great and performs well.
