Im new to RO so im not familiar with games this realistic, the closest thing i have to this is battlefield, I have deluxe pre ordered but I want tips so I don't join and die every 10 steps.
Don't get downhearted if you only get 2 or 3 (or even 1) kill per game at the start - the gameplay is completely different from everything else so it will take a while. But it is so much more satisfying getting a single good kill on this game than getting 10 kills on CoD...
