First Strike - Master Commendation Tip

I am working on some of my commendations and the First Strike Master is a lot of fun to try for. First strike in a match is tough but I have found a way to better my odds. Play Flood game type and triple your chances in less time. Flood has three rounds per match and each one gives a first strike medal. I didn't like playing flood at first until I realized that while all the other spartans are looking for camping grounds I could be hunting the flood and getting first strike every time (unless they get me). It is actually very enjoyable when you go on the offense as a spartan instead of focusing on defense. I got 20 first strike medals in less than two hours last night. One game I got it in all three rounds of the match.
