improve at first person shooters IRP Q2 post #3

Another update on how i am doing in getting better at first person shooters, i started playing a few matches of free for all and was doing trash for a bit until i went to see if i can do anything better that might be able to help me. So i found this text in my book "stay out of open areas, but utilize windows and cover that over looks them in order to grab kills at a distance"(Primagames45)
this piece of information helped me a lot because as you can see i went off and went 30 and 3. After this game i felt good, and i am wondering have you guys ever got any good KD ratio games like this? And i basically just stayed on the outskirts of the map instead of going to the middle where the area is open.
