There is only one way to get 8 kills in a round on Socom II. Of course there has to be 8 people on the other side, Your team has to really suck, and you have to have some skill and some luck on your side. I have gotten 8 kills in a round three times. Twice on abandoned and once on shadow falls. The abondoned maps was with an m14 and shadow falls was sniping with the help of some mines. I have had mulitple seven round kills. Most of them on Chain Reaction, but I feel like I have had at least a six or seven kill round on almost every map. My best map overall is Chain Reaction and I have done as good as 33-2 and 30-2 on that map as a seal and 27-4 as a terrorist. I usually get at least 20 kills as a seal or terrorist on that map.
I used to play with this guy named PinkyC all the time that would repeatedly get high twentys or thirty kills every time and then he started playing Final Fantasy...loser.
I like the guys story about sandstorm. That was cool.
