... when looking a the rankings, I noticed that there were some individuals that are ranked 12, 18, 22, etc. When entering games like this, it is difficult to get enough experience to survive for more than a few moments.
I found the MP for FC2 quite difficult in comparison to other MP games. I died quite quickly too. For any online games, one of the biggest keys is to learn the maps. Once you know the layouts and where the other team spawns at, it helps considerably. You'll learn where others like to hide and snipe from etc. as well.
